# Lesson 7

Relate Multiplication and Division

### Lesson Purpose

The purpose of this lesson is for students to use the relationship between multiplication and division to write equations and solve problems.

### Lesson Narrative

In previous lessons, students built a foundation of division understanding and connected multiplication and division equations. Here, they use a variety of representations to show how multiplication and division are related and write multiplication or division equations to represent division situations.
