Lesson 9
All Kinds of Numbers on the Number Line
Lesson Purpose
The purpose of this lesson is for students to use their knowledge of fractions on the number line to locate 1 when given a nonunit fraction.
Lesson Narrative
Previously, students have located fractions on the number line, including locating 1 when given a unit fraction. In the first activity, students reinforce their understanding of the numerator and denominator of a fraction as they find 1 given a fraction greater than 1. They use the numerator of the given fraction to identify the size of a unit fraction and then to locate 1. Later, they locate a nonunit fraction given the location of a unit fraction with a different denominator. There, students use their knowledge of locating 1 first and then locating the nonunit fraction from 1.
The second activity in this lesson is optional because it goes beyond the depth of understanding required to address grade 3 standards.
