Lesson 13.1 Rectangles: Fixed Area

This lesson reviews area and perimeter of rectangles, requiring students to create different rectangles with a given fixed area. All lessons in the geometry cluster emphasize algebra connections and use of the fourfold way.

Some features in the Student Pages that employ the use of the fourfold way: pictures   drawing rectangles to fit prescribed situations (SP2-3)   graphing points in the coordinate plane (SP1, 5-8) numbers   finding length, perimeter, and area by counting (SP1-2, 4 -7)   recording data in tables (SP2, 4-7) symbols   finding length, perimeter, and area using formulas (SP1-2, 4-8) words   oral: discussion with peers and answering teacher questions   written: answering questions about information in tables and graphs, making conjectures based on patterns, and explaining formulas (SP2-8)
