EngageNY 60 min(s)Support for English Language Learners

In this lesson, students learn to decompose a whole into three equal parts to create thirds. They create fourths by splitting two halves into two equal parts. Given a variety of partitioned shapes, students are asked to determine how many thirds or fourths are represented by the shaded (or unshaded) portion.
