# Lesson 5

Write Division Expressions

### Lesson Purpose

The purpose of this lesson is for students to write division expressions to represent division situations and solve “how many groups?” and “how many in each group?” problems.

### Lesson Narrative

Students sort division situations for whether the number of groups is unknown or the number of objects in each group is unknown and write division expressions to represent each situation (MP2). Students then have a chance to use the representations they have learned in this section to solve division problems.
