Side Length, Perimeter, and Area of a Rectangle
Activity Overview
Explore the effects of changing base (or height) of a rectangle on it's perimeter and area.
Objectives
- Explain how a change in only the base (or the height) of a rectangle affects its perimeter
- Explain how a change in only the base (or the height) of a rectangle affects its area
Vocabulary
- base
- height
- perimeter
- area
About the Lesson
In this lesson, students will change the base of a rectangle and observe the corresponding changes in the perimeter and area. They will also change the height of a rectangle and observe the corresponding changes in the perimeter and area. As a result. students will:
- Generalize the effect on perimeter when the base (or height) is increased by n units.
- Generalize the effect on area when the base (or height) is increased by n units.
