This Instructional Activity is a part of the Lesson 13, Unit 4, Grade 6. This activity serves two purposes: To review and illustrate the idea from grade 5 that the area of a rectangle with fractional side lengths can be found by multiplying the two fractions, just as in the case of whole numbers. To prepare students to reason about a prism with fractional edge lengths. Students connect the area of a square with fractional side length with that of a unit square.
