Unit 3, Lesson 18
Represent Situations with Multiplication and Division
Grade 5
Preparation
Lesson Purpose
The purpose of this lesson is for students to apply their understanding of fraction multiplication and division to solve problems in context.
Lesson Narrative
In previous lessons, students multiplied fractions and divided whole numbers and unit fractions. They represented situations by drawing diagrams, writing expressions and equations, and solving problems using numerical methods.
In this lesson, students continue to solve problems in context with a goal of understanding how to solve them using either multiplication or division. Students create and interpret diagrams, and explain how the same diagram can be interpreted as representing multiplication or division.
- Engagement
- MLR1
- Generate both multiplication and division equations to represent situations in context.
- Justify (orally) that either a division or a multiplication equation can represent the same situation.
- Let’s represent problems with multiplication and division equations.
Required Preparation
None
