This 7th grade Math parent guide explains the content in straightforward terms so they can support their children’s learning at home and will encourage caretaker engagement with lessons.
Our Teacher Guides are meant to support the use of our online course and unit content. Please use these to accompany the use of our content and for ideas to support struggling learners, those needing extension and for additional resources.
This word problem requires students to use fractions to solve it.
Students will be asked to evaluate their local community and design and build a 3-dimensional circular space, building, or facility to meet their town's / city's / state's needs. Requirements: two written paragraphs, blueprints drafted on graph paper, a physical model, a Project Improvement Plan, and self reflection.
In this activity, students will find discounts and sale prices for items selling at 20% off and 40% off by using tables. They will then find the general rules, using a variable, for finding those discounts and prices.
In this lesson, students perform various calculations involving rational numbers to solve a problem related to the change in an investment's balance over time. Students recognize and use mathematics as a tool to solve real-life problems.
In this activity, students will use the CelSheet App that multiplies the fraction by “1” to help determine the common denominator. Then they will use what they have learned to add and subtract fractions without the same denominators. As an extension, they will use the LCM command to quickly obtain the best denominator to complete the operations.
In this lesson, students calcuate the out-of-pocket money needed to purchase a discounted item taxed at a certain percentage of sales tax.
In this lesson, students create equivalent forms of expressions in order to see structure, reveal characteristics, and make connections to context. Students compare equivalent forms of expressions and recognize that there are multiple ways to represent the context of a word problem. Students write and evaluate expressions to represent real-world scenarios.
Students will use an Integer Card Game that creates a conceptual understanding of integer operations and serves as a mental model students can rely on during the module. They will build on their understanding of rational numbers to add, subtract, multiply, and divide signed numbers.
This lesson unit is intended to help teachers assess how well students are able to interpret percent increase and decrease, and in particular, to identify and help students who have the following difficulties: translating between percents, decimals, and fractions; representing percent increase and decrease as multiplication; and recognizing the relationship between increases and decreases.
For this interactive, students solve word problems using mixed operations.
In this activity, students review the definition of rational numbers as ratios and as terminating and repeating decimals. They also examine the reciprocal property of rational numbers and operations with rational numbers.

Students understand that if a number sentence is true and we make any of the following changes to the number sentence, the resulting number sentence will be true:
Adding the same number to both sides of the equation, If a = b, then a + c = b + c
Subtracting the same number from both sides of the equation, If a = b, then a - c = b - c
Multiplying each side of the equation by the same number, If a = b, then a( c )= b( c )
Dividing each side of the equation by the same nonzero number, If a = b and c ≠ 0, then a ÷ c = b ÷ c
Students revisit the integer game to justify the above referenced if-then statements.
Students are introduced to several types of common medical sensor devices, such as ear and forehead thermometers, glucometers and wrist blood pressure monitors; they use the latter to measure their blood pressure and pulse rates. Students also measure their heights and weights in order to calculate their BMIs (body mass index). Then they use the collected data to create and analyze scatterplots of the different variables to determine if any relationships exist between the measured variables. Discussions about the trends observed and possible health concerns conclude the activity.
This task requires students to be able to reason abstractly about fraction multiplication as it would not be realistic for them to solve it using a visual fraction model. Even though the numbers are too messy to draw out an exact picture, this task still provides opportunities for students to reason about their computations to see if they make sense.
In this activity, students will increase their understanding of the use of the formula T = r ? p, which is encountered both in the real world and in most Algebra classes. They will calculate the amount of taxes and tips exactly, and then use estimation.
