Lesson 2

Name Parts as Fractions

Lesson Purpose

The purpose of this lesson is for students to partition shapes into equal parts and express each equal-size part as a unit fraction.

Lesson Narrative

Previously, students partitioned rectangles that each represented 1 into fractional parts by folding. They now draw lines to partition a shape and use the fraction notation they learned to label each part as a unit fraction and describe a shaded part as a unit fraction. This lesson is the first time that students work with fraction strips, which will be used multiple times in the unit.
