Lesson Plan: Area of Irregular Shapes
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to estimate the areas of some irregular shapes using a grid of unit squares.
Objectives
Students will be able to
- estimate the area of an irregular shape by counting unit squares,
- identify whether an estimate is more or less than the actual area,
- compare two irregular shapes by their area.
Prerequisites
Students should already be familiar with
- finding the area of composite rectilinear shapes.
Exclusions
Students will not cover
- calculating the area of irregular shapes.
