Draw different rectangles with the same area but different perimeters on graph paper.
Clarifications:
Essential Understandings
Concrete:
- Use manipulatives to model rectangles.
- Use manipulatives to model rectangles with the same area, but different perimeters (e.g., area = 12: length = 6, width = 2 OR length = 3, width = 4).
- Use visual representations of various figures and sizes.
- Understand that shapes could have the same area, but may look different (i.e., have a different length and width).
- Create shapes that have the same area, but have a different perimeter (i.e., length and width).
- Understand the following concepts and vocabulary: perimeter, area, sides, rectangle, factor, array, length, and width.

Cluster:
Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures. (Additional Cluster) :
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
