# Lesson 14

### Lesson Purpose

The purpose of this lesson is for students to solve problems using information presented in line plots.

### Lesson Narrative

Previously, students organized and analyzed measurement data on a line plot. They also learned to express equivalent fractions (for example, they expressed 3 fourths as 6 eighths). In this lesson, they continue to use these skills, along with their knowledge of addition and subtraction of fractions with the same denominator, to solve problems involving fractional measurements.
