This Instructional Activity is a part of the Lesson 1, Unit 8, Grade 8. In this activity, students use squares with known areas to determine the total area of five shapes. How students determine the area of the shapes is left open-ended on purpose. Students may calculate each shape individually, or, with a bit of rearranging, they may "fit" the shapes into the squares. It is possible to fit all 5 shapes into the two smaller squares or into the one larger square. Identify groups who calculate the area of the shapes individually versus those fitting the shapes into squares.
