**Subject Area:**Mathematics

**Grade:**7

**Domain-Subdomain:**Expressions & Equations

**Cluster:**Level 1: Recall

**Cluster:**Use properties of operations to generate equivalent expressions. (Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

## Problem-Solving Tasks

Students are asked to determine if two expressions are equivalent and explain their reasoning.

Type: Problem-Solving Task

In this task students are asked to write two expressions from verbal descriptions and determine if they are equivalent. The expressions involve both percent and fractions. This task is most appropriate for a classroom discussion since the statement of the problem has some ambiguity.

Type: Problem-Solving Task

## Tutorial

This video models solving equations in one variable with variables on both sides of the equal sign.

Type: Tutorial

## Virtual Manipulative

This virtual manipulative allows the learners to solve simple linear equations through the use of a balance beam. Unit blocks and* x*-boxes are placed on the pans of a balance beam to balance it.
