# Lesson 12

Solving Problems Involving Fractions

### Lesson Narrative

In this lesson, students use their understanding of and their facility with all four operations to represent and solve problems involving fractions. The last activity requires students to make sense of the problem and persevere in solving it (MP1).

Teacher Notes for IM 6–8 Accelerated
This lesson is optional. These activities give students more opportunities to apply operations with fractions to solve problems in real-world situations.

### Learning Goals

Teacher Facing

• Apply operations with fractions to solve problems in a variety of situations, and explain (orally and in writing) the reasoning.
• Generate an equation to represent a situation involving fractions, and justify (orally) the operation chosen.

### Student Facing

Let’s add, subtract, multiply, and divide fractions.

### Required Preparation

For the second activity (Pairs of Problems), plan an efficient way to assign at least 1 division problem and 1 problem involving another operation to each student (or group).

### Student Facing

• I can use mathematical expressions to represent and solve word problems that involve fractions.
