Unit 2, Lesson 15
Multiply More Fractions
Grade 5
Preparation
Lesson Purpose
The purpose of this lesson is for students to apply their understanding of the properties of operations to multiply whole numbers and fractions greater than 1 written as mixed numbers.
Lesson Narrative
In previous lessons, students used the properties of operations to write equivalent expressions in order to find products of fractions greater than 1 written as mixed numbers.
In this lesson, students apply their understanding of the properties of operations to multiply whole numbers and fractions greater than 1 written as mixed numbers. In each activity, encourage students to think flexibly, using everything they have learned about fraction decomposition, multiplication, and the properties of operations.
- Engagement

- Match (orally and in writing) diagrams and expressions that represent the same way to calculate the product of a whole-number and a fraction.
- Let’s multiply mixed numbers.
Required Preparation
