The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for assessing grade-level content. The assessments are aligned to grade-level standards. Examples include:
- In Unit 3, End-of-Unit Assessment, Problem 4, students decide if the circumference and radius (7.G.4) are proportional based on the given graph and ordered pairs (7.RP.2): “A class measured the radius and circumference of various circular objects. The results are plotted on the graph. 1) Does there appear to be a proportional relationship between the radius and circumference of a circle? Explain or show your reasoning. 2) Why might the measured radii and circumferences not be exactly proportional?”
- In Unit 5, End-of-Unit Assessment, Problem 6 assesses student understanding of adding and subtracting rational numbers (7.NS.1,3) by presenting a scenario that describes a bank account in which students must calculate the balances and transaction amounts. Problems are presented with a relevant context for standards that require a real-world context.
- In Unit 8, Mid-Unit Assessment, Problem 7 assesses 7.SP.8a by presenting a game using a special deck of cards with 40 cards numbered from 1 to 40. Students find the probability for three different situations; drawing a card divisible by 2, 5, and 10 and explaining their reasoning.
Assessments are located on the first page of each unit in Lessons & Assessments, which is below Unit Overview, for each of the first eight units. Unit 9 is an optional unit and has no assessments.

The objectives for the materials are shaped by the CCSSM cluster headings, and they also incorporate natural connections that will prepare a student for upcoming grades.
Indicator {{'1c' | indicatorName}}
The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations that supporting work enhances focus and coherence simultaneously by engaging students in the major work of the grade.
Supporting standards/clusters are connected to the major standards/clusters of the grade. Multiple lessons in the Grade 7 curriculum incorporate supporting standards in ways that support and/or maintain the focus on major work standards. Examples of the connections between supporting work and major work include the following:
- In Unit 2, Lesson 8, Activity 3, students analyze relationships between side length and total edge length, volume, and surface area (7.G.6) and determine if they are proportional or non-proportional (7.RP.2). Students also practice calculating volume and surface area of three-dimensional figures (7.G.6) while exploring, discussing, and proving whether relationships are proportional.
- In Unit 3, Lesson 3, Activities 1 and 2, students measure and plot the diameter and circumference of circles (7.G.4), determine if they are in a proportional relationship, and find the constant of proportionality (7.RP.2). In Activity 2, students are provided one measurement (diameter or circumference) and use the derived constant of proportionality to determine the other.
- In Unit 3, Lesson 5 (optional), 7.G.4 is connected to 7.RP.2,3. The Activities include contexts in which students use diameter and circumference relationships to calculate how far wheels (circles) can roll to reach certain distances and explore rotations per second and time traveled. In Unit 3, Lesson 7, students explore the proportionality between diameter and area to determine that they are not proportional.
- In Unit 7, Lesson 16, the Activities provide students with complex surface area and volume contexts in which students use proportional relationships situated in real-world problems (7.G.6, 7.RP.A). In Activity 2, students are given some dimensions and the area of a base of a hexagonal prism. Students find the total number of bags of sand that were poured into the prism to reach a certain height. Students use concepts related to surface area, volume, and proportional reasoning to answer subsequent questions, including determining how many more bags would be necessary to fill the prism (sandbox) an additional 3 inches.
- In Unit 8, Lessons 4, 7, 16 and 20, statistical work with simulations and populations is used in coordination with proportional reasoning as students explore experimental probability and statistical sampling (7.SP.C, 7.RP.A).
- In Unit 7, Lesson 5, Activities involve students using equations to represent angle relationships and solve for unknown angles. Angle relationships involve setting up simple and multi-step equations (7.EE.4, 7.G.5).

Indicator {{'1e' | indicatorName}}
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for being consistent with the progressions in the standards. The instructional materials clearly identify content from prior and future grade levels and use it to support the progressions of the grade-level standards. The instructional materials also relate grade-level concepts explicitly to prior knowledge from earlier grades.
The materials are intentionally designed to address the standards the way they are laid out in the progressions, and the full unit narrative in the Unit Overview describes how the standards and progressions are connected. Units begin with lessons connected to the standards from prior grades that are relevant to the current topic. Standards from the grade level and prior grades and standards that will be addressed later in the year are identified in the sections as “addressing,” “building on,” and “building towards,” respectively. For example:
- In the Full unit narrative, Unit 1 is connected to geometry and geometric measurement found in earlier grades. The tasks in the unit are built upon work “composing, decomposing, and identifying shapes” in Grades 1 and 2, “distinguishing area and perimeter” from Grade 3, “[applying] area and perimeter formulas” in Grade 4, “[extending] the formula for the area of a rectangle to include rectangles with fractional side lengths” in Grade 5, and finally, generating formulas for the area of parallelograms and triangles in Grade 6. The unit addresses Grade 7 work with scale drawings as students “reason about the scaled copies of figures” leading to work with proportions in Unit 4 and extends this knowledge in Grade 8 when they will work with transformations.
- In Unit 5, Lesson 5 identifies 1.OA.4 as the standard that the lesson is “building on,” the standard the lesson is “addressing” is 7.NS.1c, and the standard the lesson is “building toward” is 7.NS.1. The lesson builds on Grade 1 understanding of subtraction and extends it to adding and subtracting rational numbers in the first lessons in the unit. By Lesson 15, rational numbers are embedded in expressions and equations. The following explanation is provided for teachers: “The purpose of this lesson is to get students thinking about how to solve equations involving rational numbers. In Grade 6, students solved equations of the form px=q and x+p=q and saw that additive and multiplicative inverses (opposites and reciprocals) were useful for solving them. However, that work in Grade 6 did not include equations with negative values of p or q or with negative solutions. This lesson builds on the ideas of the last lesson and brings together the work on equations in Grade 6 with the work on operations on rational numbers from earlier in Grade 7.”
The Warm-Ups in lessons frequently work with prior-grade standards in ways that support learning of grade-level problems and make connections to progressions from previous grades. For example:
- The Unit 2, Lesson 7 Warm-Up includes equivalent ratio context (6.RP.3) that builds to an expectation of students using proportional relationship language in context (7.RP.2). These precede two lessons where students explore the difference between proportional and nonproportional relationships.
- The Unit 5, Lesson 9 Warm-Up uses an image of a woman in stride and asks students to estimate where the woman will be in five seconds and where she was five seconds before. This activity builds off constant speed contexts in Grade 6 (6.RP.3b) and primes students for considering negative time and velocity (7.NS.3 and 7.RP.2).
The instructional materials attend to the full intent of the grade-level standards by giving all students extensive work with grade-level problems.
In the Course Guide under Course Information and Scope and Sequence, there is a chart which accurately reflects the mathematics in the materials. All grade-level standards are represented across the 9 units. Tasks are aligned to grade-level work and are connected to prior-grade knowledge. For example:
- Unit 2 introduces proportional relationships and is strategically divided into sections that explore conceptual understanding through comparing proportional and non-proportional relationships, tabular and graphic representations, as well as equations in the form of y = kx. The Lesson 1 through 3 Warm-Ups explore ratios and patterns in tables and are connected to 6.RP.A. Lessons 4 through 6 focus on representing proportional relationships with equations with different contexts.
- In Unit 7, the first five lessons focus on angle relationships. The first two lessons focus on making connections to the additive nature of angle measures found in 4.MD.6 and 4.MD.7. Lesson 1 in this unit states, “Students were introduced to angles in Grade 4, when they drew angles, measured angles, identified angles as acute, right, or obtuse, and worked with adding and subtracting angles. Earlier in Grade 7, students also studied angles briefly in their work with scale drawings. Now they begin a more detailed study of angles. In this lesson, students gain hands-on experience composing, decomposing, and measuring angles. They refresh their memory about the relationship between right angles, straight angles (180 degrees), and ‘all the way around’ angles (360 degrees), and they fit pattern blocks around a point to find out the angles at their vertices.” The lessons then explore the properties of angles including solving for unknown angles. According to the CCSS Progressions for Grade 7, students build on earlier experiences with angle measurement to solve problems that involve supplementary angles, complementary angles, vertical angles, and adjacent angles.
A typical lesson has a Warm-Up, one or more Activities, and a Cool-Down. Additionally, every lesson provides practice problems that can be used as independent or group work. Some lessons also provide an “Are you ready for more?” question. These problems are an opportunity for students to explore grade-level mathematics in more depth and often make connections between the topic in the lesson and other concepts at grade level. They are intended to be used on an opt-in basis by students if they finish the main class activity early or want to do more mathematics on their own.
Indicator {{'1f' | indicatorName}}
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for fostering coherence through connections at a single grade, where appropriate and required by the standards.
Materials include learning objectives that are visibly shaped by CCSSM cluster headings, including:
7.RP.A Analyze proportional relationships and use them to solve real-world and mathematical problems.
- The Unit 2 Overview includes unit goals to understand terms and concepts related to proportionality and to recognize relationships that are proportional. Specific types of real-world situations that are used in the unit (constant speed, unit pricing, and measurement conversion) are also described. Lesson 1 begins with tasks from Grade 6 that involve analyzing differences between situations that require equivalent ratios and those that do not; in Lessons 2 and 3, students explore proportional relationships and develop formal terminology; in Lessons 7 through 9 students analyze aspects of proportional relationships as they compare to non-examples of proportional relationships; and Lessons 10 through 13 continue the work of representing and analyzing proportional relationships by comparing graphs and equations of proportional relationships.
- In Unit 2, Lesson 9, the learning targets are visibly shaped by the cluster heading and state, “I can solve all kinds of problems involving proportional relationships,” and “I can ask questions about a situation to determine whether two quantities are in a proportional relationship.”
7.EE.A Use properties of operations to generate equivalent expressions.
- Learning goals for Unit 6, Lessons 18 through 22 are developed from the cluster heading, including: “Use a graphic organizer for work with the distributive property.” “Understand how to rewrite subtraction as adding the opposite in order to use the commutative property.” “Apply the distributive property to expand and factor linear expressions with rational coefficients.” “Apply properties of operations to generate an equivalent expression with fewer terms.” “Identify and correct errors made when applying properties of operations.” and “Generate a variety of expressions by positioning parentheses in different places in a given expression; apply properties to write the expressions with fewer terms.”
7.EE.B Solve real-life and mathematical problems using numerical and algebraic expressions and equations.
- In Unit 6, Lesson 11, the learning target is shaped by the cluster heading, stating, “I can solve story problems by drawing and reasoning about a tape diagram or by writing and solving an equation.”
The materials consistently include problems and activities that connect two or more clusters in a domain or two or more domains in a grade, in cases where these connections are natural and important. Multiple examples of tasks connecting standards within and across clusters and domains are present.
- Unit 1, Lesson 6, Activities 1, 2, and Lesson Cool-down connect 7.G.A and 7.G.B when students use scale drawings to compute actual lengths and area to solve real-world problems involving geometric figures.
- In Unit 5, Lesson 12, Activities 3 and 4, students apply proportional reasoning when using equations including a negative constant of proportionality (7.EE.B and 7.RP.A) and solve real-world problems using all four operations which include rational values (7.NS.A) as they solve problems in the context of submarines. Lessons 14 through 17 include varying scenarios that involve interpreting rational values in the context of the given problem and operations with rational values.
- In Unit 6, Lesson 18, Activities 1 and 2 connect 7.NS.A and 7.EE.B. In Activity 1, students recall that subtracting a rational number or expression is the same as adding its additive inverse, and Activity 2 builds understanding of creating equivalent expressions by applying properties of operations.
Overview of Gateway 2
Rigor & Mathematical Practices
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet the expectation for aligning with the CCSS expectations for rigor and mathematical practices. The instructional materials attend to each of the three aspects of rigor individually, and they also attend to the balance among the three aspects. The instructional materials emphasize mathematical reasoning, identify the Mathematical Practices (MPs), and attend to the full meaning of each practice standard.
Gateway 2
Criterion 2.1: Rigor
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet the expectations for rigor and balance. The materials meet the expectations for rigor as they help students develop conceptual understanding, procedural skills, and application with a balance of all three aspects of rigor.
Indicator {{'2a' | indicatorName}}
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for developing conceptual understanding of key mathematical concepts, especially where called for in specific standards or cluster headings. The materials include problems and questions that develop conceptual understanding throughout the grade level, and multiple opportunities exist for students to access concepts from different perspectives and independently demonstrate conceptual understanding throughout the grade.
In Unit 6, students develop conceptual understanding of equivalence through the manipulation of expressions, using the properties of operations in order to identify and generate equivalent expressions (7.EE.A).
- In Lessons 2 through 5, students develop an understanding of equations as they manipulate equal parts, different parts, and the total parts related. Students also label terms in a model to represent a given context, write their own contexts, and develop the corresponding equation.
- In Lesson 7, students use “hanger diagrams” to model and maintain equivalency in equations.
- In Lessons 20 through 22, students use multiple strategies, including expanded form with variables, partitioned rectangle areas, and properties of operations, to simplify expressions and identify equivalent expressions (7.EE.1). In Lesson 20 Activity 2, students “Replace each ? with an expression that will make the left side of the equation equivalent to the right side. (Set A: 6x + ? = 10x, 6x + ? = 2x, 6x + ? = -10x, 6x + ? = 0, 6x + ? = 10).” Students respond to questions: “Why didn't you combine x terms and numbers?” “How did you decide on the components of the missing term?” “Did you use the commutative property?” “Did you use the distributive property?” “What are some ways we can tell that 7x+2 is not equivalent to 9x?” “Someone is doubtful that 3b−8b is equivalent to -5b, but they do understand the distributive property. How could you convince them that these expressions are equivalent?” “What are some ways we could rearrange the terms in the expression -2x + 6y − 6x + 15y and create an equivalent expression?” In this activity, students develop and articulate their understanding of equivalent expressions.
Unit 5 addresses applying and extending previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers, 7.NS.A:
- In Lesson 2, students add and subtract rational numbers on the number line (7.NS.1). In the first Activity, students draw number lines, write equations, and verbally explain number line movement. A thermometer applet, which students can manipulate to represent the given situation, is included in the second Activity. Arrows are applied within the applet, and the thermometer context serves as a vertical number line representation on which students add integers.
- In Lesson 3, conceptual understanding is extended as students apply the information from given situations to visually model elevation change (7.NS.1).
- The Lesson 4 Introduction explains that students will use money as a way “to practice performing operations on signed values, but the emphasis is really on noticing that money can be represented with positive and negative values.” The Overview further describes conceptual understanding with: “Any situation in which we use a negative number to represent a debt (for example), we could equally well just use a positive number and distinguish it by calling it a debt. The reason we use signed numbers in this context is that it allows us to represent a whole class of problems with the same expression. For example, if a person has $50 in the bank and writes a $20 check, we can represent the balance as 50−20. If they had written an $80 check, we can still write the balance as 50−80, as long as we have adopted the convention that negative numbers represent what the person owes the bank (and assuming the bank allows overdrafts).”
- Lessons 8 through 12 address multiplication and division (7.NS.2). In Lesson 8, students explore multiplication of a negative and a positive value in terms of speed in a certain direction over a number of seconds. Students use a number line and a table to establish a pattern. For example, one row in the table states: “starting at zero” “left” “4 units per second” “6 seconds.” Students use a number line to come up with the equation. In Lesson 9, students determine the pattern for multiplying two negative values (7.NS.2). Building on the understandings developed in Lessons 8 and 9, students use the relationship between multiplication and division to develop rules for dividing signed numbers in Lesson 11.
Indicator {{'2b' | indicatorName}}
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for attending to those standards that set an expectation of procedural skill and fluency. Materials attend to the Grade 7 expected procedural skills, particularly those related to rational numbers and solving equations.
Procedural skills and fluencies develop with conceptual understanding and are built upon work students have accomplished with operations and equations from prior grades. Students practice developed procedures throughout practice problem sets that follow the units, and students use emerging fluencies in the context of solving problems. According to the Design Principles within the Grade 7 Course Guide, “As the unit progresses, students are systematically introduced to representations, contexts, concepts, language, and notation. As their learning progresses, they make connections between different representations and strategies, consolidating their conceptual understanding, and see and understand more efficient methods of solving problems, supporting the shift towards procedural fluency. The practice problems give students ongoing practice, which also supports developing procedural proficiency.” Number Talks included in many Warm-Ups often revisit fluencies developed in earlier grades and specifically relate to the Activities found in the lessons. Additionally, students demonstrate procedural skills throughout the year in a variety of practice problems. Examples of practice problems include:
- In Unit 6, Lesson 10, 10.4 Cool-down, students solve equations such as “8.88 = 4.44(x - 7)” (7.EE.4a).
- In Unit 5, students perform computations with integers in Lessons 2 through 12 and rational numbers within expressions and equations in Lessons 13 and 17 (7.NS.A):
- Lesson 5 introduces subtracting integers with number lines, the coordinate plane, tables, and the relationship between addition and subtraction of integers, and students solve expressions with rational numbers. In Lesson 7, students apply their knowledge of operations with integers to real-world problems. Multiplying integers is introduced in Lesson 8 with additional opportunities to build procedural skill in Lessons 9 through 11.
- In Lesson 11, Items 1-4 provide practice with multiplication and division with rational numbers.
- The Lesson 13 Warm-Up includes true/false reasoning with signed numbers. The first Activity, a Card Sort, states: “In this activity students continue to build fluency operating with signed numbers as they match different expressions that have the same value.” The cards include both integers and fractions.
- In Unit 6, procedural fluencies with grade-level operations are revisited in the Lesson 18 and 19 Warm-Ups in preparation for working with equations including rational numbers. In Lessons 18 through 22, students work with rational numbers and negative terms (7.EE.1) in ways that continue to build fluency when computing with signed numbers.
In Unit 6, students use properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients (7.EE.1).
- In Lesson 19, Activity 1, students factor and expand expressions with signed numbers in the given table. The following Cool-Down Activity includes two more opportunities to expand and factor equations with rational values.
- In Lesson 20, Activity 1, students use properties of operations to justify equivalence of expressions. In Activity 2, students fill in missing terms to balance equations and are provided questions such as, “How did you decide on the missing components of the term?” to develop the procedures of combining like terms.
Indicator {{'2c' | indicatorName}}
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for being designed so that teachers and students spend sufficient time working with engaging applications of the mathematics. Engaging applications include single and multi-step problems, both routine and non-routine, presented in a context in which the mathematics is applied. Applications occur throughout the materials and are used throughout the curriculum to build conceptual understanding.
In several Units, students work with speed and water filling/draining contexts in increasingly complex ways and also use proportional reasoning skills (7.RP.A) in more complex and non-routine ways alongside work with surface area/volume and later with probability. Examples include:
- In Unit 2, Lesson 5, students are given a rate for water filling an object, find multiple equations that model the situation, and identify and interpret the rates in context. The lesson introduction states: “Students are expected to use methods developed earlier: organize data in a table, write and solve an equation to determine the constant of proportionality, and generalize from repeated calculations to arrive at an equation.”
- In Unit 2, Lesson 6, students determine the constant of proportionality in the context of concert ticket sales, recipes, and recycling. In Lesson 7, students make adjustments to quantities used in recipes, compare costs for various group sizes to enter a state park, and determine if several runners are moving at a constant pace. In the last context, students reason about making determinations about proportionality in a discrete context (7.RP.2a) and their inability to establish proportionality given a continuous relationship when considering the limitations of intervals in the table.
- In Unit 4, Lesson 10, students apply percentage to taxes and tips. Activity 1 provides students with two tables giving the sales tax charges on the same items in two different cities. Students complete the table, find the tax rate in each city, and compare them. Activity 2 adds another city to the problem, and students realize through their calculations that the tax amount must be rounded.
- In Unit 4, Lesson 16, students sort actual newspaper clippings, decide if they are percents of increase or decrease, choose a clipping that is interesting to them, and “create a visual display that includes: a title that describes the situation, the news clipping, your diagram of the situation, the two questions you asked about the situation, the answers to each of your questions, [and] an explanation of how you calculated each answer.”
- In Unit 5, Lesson 8 Warm-Up, three problem scenarios are given in which students apply understanding of proportional relationships in a constant speed context. Students first find the total distance a plane travels in prompt 1; the speed of a train in prompt 2; and the time a car traveled in prompt 3. This work prepares students for thinking about contexts involving negative numbers in context of velocity, time, and position.
- In Unit 7, Lesson 16, students apply understanding of proportional relationships to find surface area and volume and the total cost of constructing a ramp in a non-routine problem context. Activity 2 presents another non-routine problem involving surface area, volume, and using proportional relationships: “The daycare has two sandboxes that are both prisms with regular hexagons as their bases. The smaller sandbox has a base area of 1,146 square inches and is filled 10 inches deep with sand.” The following prompts accompany the given real-world scenario: “It took 14 bags of sand to fill the small sandbox to this depth. What volume of sand comes in one bag? (Round to the nearest whole cubic inch.); The daycare manager wants to add three more inches to the depth of the sand in the small sandbox. How many bags of sand will they need to buy?; The daycare manager also wants to add three more inches to the depth of the sand in the large sandbox. The base of the large sandbox is a scaled copy of the base of the small sandbox, with a scale factor of 1.5. How many bags of sand will they need to buy for the large sandbox?; A lawn and garden store is selling six bags of sand for $19.50. How much will they spend to buy all the new sand for both sandboxes?”
In Unit 6, students solve multi-step real-life and mathematical problems with rational numbers in various forms (7.EE.3). Examples include:
- In Lesson 2, students encounter many routine problems that require algebraic thinking to solve: “Noah’s family bought some fruit bars to put in the gift bags. They bought one box each of four flavors: apple, strawberry, blueberry, and peach. The boxes all had the same number of bars. Noah wanted to taste the flavors and ate one bar from each box. There were 28 bars left for the gift bags.” Students use tape diagrams to establish a context for equations of the forms p(x+q)=r and px+q=r.
- In Lesson 12 Activity 1, students use the given tape diagram and sample student responses to make connections between the context (change in temperature over three days) and equations that model contexts involving percent increase. In Activity 2, students solve four multi-step real-world problems. In the Cool-Down, students write and solve an equation for this problem: “The track team is trying to reduce their time for a relay race. First, they reduce their time by 2.1 minutes. Then, they are able to reduce that time by 1/10. If their final time is 3.96 minutes, what was their beginning time? Show or explain your reasoning.”

The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations that the three aspects of rigor are not always treated together and are not always treated separately. The materials address aspects of rigor independently, and there are instances when multiple aspects of rigor are used to support student learning and mastery of the standards. There are multiple lessons where one aspect of rigor is emphasized.
Examples of conceptual understanding include:
- In Unit 6, Lessons 7 and 8 intentionally isolate the conceptual understanding related to solving equations in the form of px + q = r and p(x+q) = r by using hanger diagram models to visualize balance between the sides of an equality (7.EE.4a).
- In Unit 6, Lesson 18, Activity 1, students use area models to develop conceptual understanding of how the distributive property works with both positive and negative terms. In the Lesson Synthesis, students develop a conceptual understanding on how the commutative property works with addition but not subtraction.
Examples of procedural skills and fluency include:
- In Unit 6, Lesson 10, students develop procedural skills in solving equations, 7.EE.4, by sharing their solution strategies. The Warm-Up involves an Algebra Talk where students have 30 seconds to think about methods of solving and solutions to five different problems in p(x+q) = r form. In Activity 1, students perform an error analysis of given students’ methods. In Activity 2, students solve five problems using two different methods and compare them. This task also prompts students to evaluate more inefficient methods and explain why they are not effective.
- In Unit 6, Lesson 22 Overview states that “students have an opportunity to demonstrate fluency in combining like terms and look for and make use of structure (MP7) to apply the distributive property in more sophisticated ways.” In Activity 1, students match equivalent expressions which include negative terms with a partner.
Examples of application include:
- In Unit 2, Lesson 15, students answer whether baths or showers use more water (7.RP.2). Students determine what information they would need to solve the problem, gather the data/information they need, and make assumptions using what they find.
- In Unit 5, Lesson 17, students apply their understanding of percent increase and decrease and work with rational numbers to calculate changes in stock value and total value of investment portfolios in non-routine stock market situations (7.RP.3).
Examples of lessons where two or three aspects of rigor are connected include:
- In Unit 2, Lesson 14, students apply conceptual understanding of proportional relationships. Students use lists of items (creatures, length units, time units, volume units, body parts, area units, etc.) to create a situation that shows a proportional relationship between two different things in the list, describe a situation where two things are not proportional, and create a table, graph, and equation that represent the proportional/non-proportional relationship.
- In Unit 5, Lessons 1 and 2 build upon the conceptual development of negative numbers in Grade 6, including placing them on the number line, comparing and ordering them, and interpreting them in the contexts of temperature and elevation. Procedural skill is integrated with conceptual understanding and application when students draw diagrams to represent temperature changes, write equations to represent the context, and solve by adding and/or subtracting integers. In Lesson 3, students represent quantities on number lines, identify opposites, and add integers. In Lesson 4, students apply their knowledge of integers to real-world scenarios with banking. Students “understand that when representing a debt with a negative number, the additive inverse tells how much money is needed to pay off the debt.”
Criterion 2.2: Math Practices
The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet the expectations for practice–content connections. The materials identify and use the MPs to enrich the content, attend to the full meaning of each MP, support the Standards' emphasis on mathematical reasoning, and attend to the specialized language of mathematics.
Indicator {{'2e' | indicatorName}}
The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations that the Standards for Mathematical Practice are identified and used to enrich mathematics content within and throughout the grade level. All eight MPs are clearly identified throughout the materials. The MPs are initially identified in the Course Guide under the full unit narrative description of each unit within the Course Information, for example:
- In Unit 4, the full unit narrative states, “In small groups, students identify important quantities in a situation described in a news item, use diagrams to map the relationship of of the quantities, and reason mathematically to draw conclusions (MP4).”
- In Unit 7, an excerpt from the full unit narrative states, “[Students] understand and use the formula for the volume of a right rectangular prism, and solve problems involving area, surface area, and volume (MP1, MP4). Students should have access to their geometry toolkits so that they have an opportunity to select and use appropriate tools strategically (MP5).”
Within a lesson, the MPs are identified within the teaching notes accompanying the lesson in general or before each of the activities. Lesson narratives often highlight when an MP is particularly important for a concept or when a task may exemplify the identified Practice, for example:
- In Unit 2, Lesson 4, About the lesson states, “In this lesson, students build on their work with tables and represent proportional relationships using equations of the form y = kx. The activities revisit contexts from the previous two lessons, presenting values in tables and focusing on the idea that for each table, there is a number k, so that all values in the table satisfy the equation y = kx. By expressing the regularity of repeated calculations of values in the table with the equations, students are engaging in MP8.”
- In Unit 3, Lesson 4, About the lesson connects the application of the circumference formula to two math practices, “Students think strategically about how to decompose and recompose complex shapes (MP7) and need to choose an appropriate level of precision for π and for their final calculations (MP6).”
- In Unit 8, Lesson 5 narrative accompanying the first Activity states, “Students have a chance to construct arguments (MP3) about why probability estimates based on carrying out the experiment many times might differ from the expected probability.”
The MPs are used to enrich the mathematical content and are not treated separately from the content in stand-alone lessons. MPs are highlighted and discussed throughout the lesson narratives to support a teacher’s understanding of the MP itself as the teacher is provided direction regarding how the content is connected to the MP, for example:
- In Unit 5, Lesson 11, the Teaching notes in the first Activity state, “The purpose of this activity is to understand that the division facts for rational numbers are simply a consequence of the multiplication done previously. Students work several numerical examples relating multiplication to division and then articulate a rule for the sign of a quotient based on the signs of the dividend and divisor (MP8).”
- In Unit 2, Lesson 7, first Activity, students use a table to explore the cost of parking and admission per person. “These diagrams may be helpful in illustrating to them that their resulting prices are including more than one vehicle. This gives them an opportunity to make sense of problems and persevere in solving them (MP1).”
The MPs are not identified in the student materials, however, there are questions posed with activities that engage students with MPs. For example, in Unit 2, Lesson 7, first Activity, the student-facing prompt related to MP1 includes: “How might you determine the entrance cost for a bus with 50 people? Is the relationship between the number of people and the total entrance cost a proportional relationship? Explain how you know.”
Indicator {{'2f' | indicatorName}}
The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for carefully attending to the full meaning of each practice standard. The materials attend to the full meaning of each of the 8 MPs. The MPs are discussed in both the unit and lesson narratives, as appropriate, when they relate to the overall work. They are also explained within individual activities, when necessary. Over the course of the year, students have multiple opportunities to engage with the full meaning of each MP. Examples include:
MP1 - Make sense of problems and persevere in solving them.
- In Unit 2, Lesson 2, students build on their understanding of scale and try to find the scale factor. The Teaching notes state, “Students grapple with finding missing values for ratios of whole numbers presented in a table where identifying a usable scale factor.” Students must make sense of new terms and apply them to their learning specifically the constant of proportionality and proportional relationship.
MP2 - Reason abstractly and quantitatively.
- In Unit 2, Lesson 3, second Activity, students make connections between constant speed and proportional relationships, with special attention to the constant of proportionality. Students “need opportunities to make the connection to proportional relationships; students who successfully make this connection are reasoning abstractly about contexts with constant speed.”
- In Unit 4, Lesson 2, students are given the following optional problem: “In real life, the Mona Lisa measures 2 ½ feet by 1 ¾ feet. A company that makes office supplies wants to print a scaled copy of the Mona Lisa on the cover of a notebook that measures 11 inches by 9 inches. Students are asked, 1) What size should they use for the scaled copy of the Mona Lisa on the notebook cover? 2) What is the scale factor from the real painting to its copy on the notebook cover? 3) Discuss your thinking with your partner. Did you use the same scale factor? If not, is one more reasonable than the other?” An applet is provided for students to experiment and understand the problem by changing the size of the Mona Lisa (abstract). The applet will display the new dimensions of the picture, but the information given for the picture cannot be scaled to the exact size of the notebook. Further investigation with equivalent ratios will lead students to one of the many possible dimensions and scale factors appropriate for the picture (quantitative).
MP4 - Model with mathematics.
- In Unit 1, Lesson 9, students apply the mathematics they know to solve problems arising in everyday life. They create their own scale drawing of a floor plan, two different scale drawings of the state of Utah, noticing how the scale impacts the drawing, and make a scale drawing of a swimming pool.
- In Unit 4, Lesson 16, students work in groups to collect news clippings that mention percentages and sort them according to whether they are about percent increase or percent decrease, formulate questions about them, and then share their questions with other groups in a gallery walk. The purpose is for students to apply percentages in a real-world context.
MP5 - Use appropriate tools strategically.
- In Unit 1, Lesson 3, optional Activity, students use a digital platform to create scaled copies of an original figure by increasing or shrinking the dimensions with the use of a fractional scale factor. In the Activity, “Students continue to work with scaled copies of simple geometric figures, this time on a grid. When trying to scale non-horizontal and non-vertical segments, students may think of using tracing paper or a ruler to measure lengths and a protractor to measure angles.”
- In Units 1 and 3, lesson plans suggest that each student have access to a geometry toolkit. These contain tracing paper, graph paper, colored pencils, scissors, centimeter ruler, protractor, and an index card to use as a straightedge or to mark right angles. Providing students with these toolkits gives opportunities for students to select appropriate tools and use them strategically to solve problems.
MP7 - Look for and make use of structure.
- In Unit 1, Lesson 2, Warm-Up Number Talk, students review multiplication strategies and develop the idea that multiplying by a unit fraction is the same as dividing by its whole number reciprocal. Students find 7.2 x 1/9 mentally. Students are guided to think about 729 and then consider what occurs to the decimal. Students are encouraged to use the structure of base ten numbers and the properties of operations.
- In Unit 4, Lesson 4, students work with the distributive property. It is noted in the lesson that when students look for opportunities to use the distributive property to write equations in a simpler way, they are looking for and making use of structure.
MP8 - Look for and express regularity in repeated reasoning.
- In Unit 1, Lesson 2, students continue their work with corresponding parts to develop the understanding and use of scale factors. The narrative states, “Students see that there is a single factor that relates each length in the original triangle to its corresponding length in a copy - hence the scale factor.”

Teachers are instructed, “As students discuss their answers with their partner, select students to share their answers during the whole-class discussion...Invite selected students to explain how they reasoned about possible labels for each of the number lines and the units of each. After each student shares, invite others to agree, disagree, or question the reasonableness of the number line descriptions.”
- The Unit 5, Lesson 6 Warm-Up Activity Synthesis provides teachers with questions to encourage constructing viable arguments. This strategy is used repeatedly throughout the series. “To involve more students in the conversation, use some of the following questions: Who can restate ___’s reasoning in a different way? Did anyone find the value of n the same way, but would explain it differently? Did anyone find the value of n in a different way? Does anyone want to add on to ___’s strategy? Do you agree or disagree? Why?”
- In Unit 2, Lesson 4 Number Talk states, “This Number Talk encourages students to think about the numbers in division problems and how they can use the result of one division problem to find the answer to a similar problem with a different, but related, divisor...Each problem is chosen to elicit a slightly different reasoning, so, as students explain their strategies, ask how the factors impacted their product.”

In the Curriculum Guide, all of the “Instructional Routines” are fully explained.
- Algebra Talks found in the Warm-Ups set a routine for collecting different strategies. “Algebra Talks build algebraic thinking by encouraging students to think about the numbers and variables in an expression and rely on what they know about structure, patterns, and properties of operations to mentally solve a problem. Algebra Talks promote seeing structure in expressions and thinking about how changing one number affects others in an equation. While participating in these activities, students need to be precise in their word choice and use of language (MP6).”
- Think-Pair-Share routines found in the Lesson Activities provide structure for engaging students in collaboration. “This is a teaching routine useful in many contexts whose purpose is to give all students enough time to think about a prompt and form a response before they are expected to try to verbalize their thinking. First they have an opportunity to share their thinking in a low-stakes way with one partner, so that when they share with the class they can feel calm and confident, as well as say something meaningful that might advance everyone’s understanding. Additionally, the teacher has an opportunity to eavesdrop on the partner conversations so that she can purposefully select students to share with the class.”

The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 7 meet expectations for including support, accommodations, and modifications for English Language Learners and other special populations that will support their regular and active participation in learning mathematics.
The ELL Design is highlighted in the Teacher Guide and embodies the Understanding Language/SCALE Framework from the Stanford University Graduate School of Education, which consists of four principles: Support Sense-Making, Optimize Outputs, Cultivate Conversation, and Maximize Meta-Awareness. In addition, there are eight Mathematical Language Routines (MLR) that were included “because they are the most effective and practical for simultaneously learning mathematical practices, content, and language.” "A Mathematical Language Routine refers to a structured but adaptable format for amplifying, accessing, and developing students’ language."
In addition, “ELL Enhanced Lessons” are identified in the Unit Overview. These lessons highlight specific strategies for students who have a language barrier which affects their ability to participate in a given task. Throughout lessons, the use of one of a variety of instructional routines is designed to assist students in developing full understanding of math concepts and terminology. These Mathematical Language Routines include:
- MLR2, Collect and Display, in which “the teacher listens for, and scribes, the student output using written words, diagrams and pictures; this collected output can be organized, revoiced, or explicitly connected to other language in a display for all students to use.”
- MLR5, Co-Craft Questions and Problems, which “[allows] students to get inside of a context before feeling pressure to produce answers, and to create space for students to produce the language of mathematical questions themselves.”
- MLR7, Compare and Connect, which “[fosters] students’ meta-awareness as they identify, compare, and contrast different mathematical approaches, representations, and language.”
In addition, lesson narratives include strategies designed to assist other special populations of students in completing specific tasks. Examples of these supports for students with disabilities include:
- Social-Emotional Functioning: Peer Tutors. Pair students with their previously identified peer tutors.
- Conceptual Processing: Eliminate Barriers. Assist students in seeing the connections between new problems and prior work. Students may benefit from a review of different representations to activate prior knowledge.
- Conceptual Processing: Processing Time. Check in with individual students as needed to assess for comprehension during each step of the activity.
- Executive Functioning: Graphic Organizers. Provide a t-chart for students to record what they notice and wonder prior to being expected to share these ideas with others.
- Memory: Processing Time. Provide students with a number line that includes rational numbers.
- Visual-Spatial Processing: Visual Aids. Provide handouts of the representations for students to draw on or highlight.
