Lesson 1

Add, Subtract, and Multiply Fractions

Lesson Purpose

The purpose of this lesson is for students to represent and solve problems involving fraction operations. Students also reason about equivalence to compare fractions to whole numbers.

Lesson Narrative

In this lesson, students practice multiplying a fraction and a whole number and adding and subtracting fractions, including mixed numbers. They rely on their understanding of equivalence and the properties of operations to decompose fractions, whole numbers, and mixed numbers to enable comparison, addition, subtraction, and multiplication (MP7). 

If students need additional support with the concepts in this lesson, refer back to Unit 3, Section B in the curriculum materials.
