Lesson 14

Problems about Fractional Measurement Data

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.
