Lesson 7. Unit 4. Grade 3 EngageNY

This Problem Set is a part of the Lesson 7, Unit 4, Grade 3. In this lesson, pairs of students create two rectangles with the same dimensions - one with square inch tiles, and the other with square centimeter tiles, and conclude that the area of a given number of square units depends on the size of those units. Then they relate area to the commutative property, and realize that, for example, a 6-inch by 3-inch rectangle has the same area as a 3-inch by 6-inch rectangle. Finally, they examine rectangles without unit squares inside, and determine that only the side lengths are really necessary to find the area.
