Finding area of compound shapes.
This 45 minute lesson’s purpose is for the students to practice explaining to others how to find the area of compound shapes made up of triangles, parallelograms, rectangles, trapezoids, semi-circles and circles. Pictures of real objects, rather than 2D drawings are used as much as possible. Each envelope has 6 shapes and 6 formulas that the students match up. They then rotate to the next station for another set of shapes.
