Learning Intentions (Objectives)
a) Students will develop the formulas for the area of a rectangle, parallelogram, triangle, trapezoid, and circle by establishing how they are developed from one another.
b) Students will apply the formulas to solve for areas of these shapes.
Rationale (Diagnostic Results)
You often do not remember common geometric formulas such as the area of a trapezoid, parallelogram, circle, etc.
Standards Addressed in the Lesson
- Explore (Area and Perimeter)
- Explore (Area and Perimeter of Triangles)
- Watch (Area of Circles)
- Practice (Area of Circles)
- Try This! (Modifying Rectangles)
