Models for Formulas of Perimeter & Area of Rectangles
T.i.P.S.
Students must be able to use models including drawings, pictures, and manipulatives to determine the formulas for the perimeter of rectangles including the special form of a square as well as the formula for the area of a rectangle.
Example
Determine the perimeter and area formulas for each figure shown below.

4.5 Algebraic reasoning. The student applies mathematical process standards to develop concepts of expressions and equations. The student is expected to: (C) use models to determine the formulas for the perimeter of a rectangle (l + w + l + w or 2l + 2w), including the special form for perimeter of a square (4s) and the area of a rectangle (l x w)Feedback
