# Lesson 3

Interpret Equations

### Lesson Purpose

The purpose of this lesson is for students to write equations to represent division situations and relate each part of the equation to the situation.

### Lesson Narrative

In previous lessons, students developed the understanding that $$1 \div b = \frac{1}{b}$$ . In this lesson, students deepen their understanding of the relationship between division and fractions. They write equations and explain how each part of the equation corresponds to a situation.
