# Lesson 18

Números más grandes en grupos iguales

### Lesson Purpose

The purpose of this lesson is for students to solve problems involving division within 100, with quotients over 10, in a way that makes sense to them.

### Lesson Narrative

In previous lessons, students learned how multiplication and division are related. They also used strategies based on properties of operations to multiply larger numbers.

In this lesson, students use a strategy of their choice to solve division problems with larger quotients than in previous lessons. Students should be encouraged to use whatever strategy and representation makes sense to them. The problem allows teachers an opportunity to see how students apply their learning from the unit to a new problem.
