Unit 5, Lesson 11# Find the area of rectangles with mixed-by-mixed and fraction-by-fraction side lengths by tiling, record by drawing, and relate to fraction multiplication.

EngageNY 60 min(s)

In this lesson, students continue applying their knowledge of area of rectangles to rectangles with fractional sides. They use hamburger patty paper to tile larger rectangles with unknown dimensions. They discover that both of the dimensions contain fractional sides, such as 2 1/2 pieces of patty paper. Then they multiply by distributing with the area model.
