Lesson Plan: Areas of Composite Polygons Mathematics • 6th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the areas of composite polygons including shapes made of squares, rectangles, triangles, parallelograms, and trapezoids.
Objectives
Students will be able to
- find the areas of composite polygons by breaking them down into familiar 2D shapes,
- subtract areas to find the areas of shapes where one shape is cut out from another.
Prerequisites
Students should already be familiar with
- finding the areas of squares, rectangles, triangles, parallelograms, and trapezoids,
- adding, subtracting, multiplying, and dividing whole numbers within 1,000.
Exclusions
Students will not cover
- areas of composite shapes involving circles or sectors,
- conversion of area units.
