Title: Balancing Act
Description:

In this activity, students will create equivalent expressions using an online tool. Students are provided two expressions and asked to find the value of the variable to make the two expressions equal. Then, students are provided an expression and a value of the variable and asked to generate a different expression equal to the original expression. Through the online digital tool, students are able to substitute values and develop strategies for creating equivalent expressions. This provides a great opportunity for students to investigate how to solve problems using multiple methods.

Title: Grade 7 Mathematics Module 2, Topic C: Applying Operations With Rational Numbers to Expressions and Equations
Description:

In Module 2, Topic C, students problem-solve with rational numbers and draw upon their work from Grade 6 with expressions and equations (6.EE.A.2, 6.EE.A.3, 6.EE.A.4, 6.EE.B.5, 6.EE.B.6, 6.EE.B.7). They perform operations with rational numbers (7.NS.A.3), incorporating them into algebraic expressions and equations. They represent and evaluate expressions in multiple forms, demonstrating how quantities are related (7.EE.A.2). The Integer Game is revisited as students discover “if-then” statements, relating changes in player’s hands (who have the same card-value totals) to changes in both sides of a number sentence. Students translate word problems into algebraic equations and become proficient at solving equations of the form px + q = r and p(x + q) = r, where p, q, and r, are specific rational numbers (7.EE.B.4a). As they become fluent in generating algebraic solutions, students identify the operations, inverse operations, and order of steps, comparing these to an arithmetic solution. The use of algebra to represent contextual problems continues in Module 3.
