EngageNY 60 min(s)Support for English Language Learners

In this lesson, students examine incomplete arrays in order to determine that only the side lengths of a rectangle are necessary to find its area. Then they practice finding area of rectangles by multiplying the side lengths, and finding the length of a rectangle's side by dividing its area and an adjacent side length.
