Final student performance task where they apply all area concepts to design a room with specific furniture areas and a total area constraint of 40 units.

Teacher's guide for the final lesson in the sequence, a cumulative design project where students apply all area concepts to create a "Dream Room" within constraints.

Student worksheet for Lesson 11 where students practice finding the total area of composite or decomposed shapes by adding partial areas.

Teacher's guide for Lesson 11 focusing on additive area and decomposing rectangles into smaller parts to find the total area.

Student worksheet for Lesson 10 where they design multiple rectangles with the same area (16 square units).

Teacher's guide for Lesson 10 which explores the concept that rectangles with the same area can have different side lengths.

Student worksheet for Lesson 9 focusing on finding missing side lengths given the area and one side length.
