Lesson Plan: Area: Whole and Half Squares Mathematics • 3rd Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to measure the areas of shapes drawn on grids using whole and half square units and solve problems relating to whole and half squares.
Objectives
Students will be able to
- find the areas of shapes made of whole and half squares,
- combine half squares to make a whole,
- record the areas of shapes in square units,
- compare and order areas made up of whole and half squares.
Prerequisites
Students should already be familiar with
- finding areas by counting unit squares,
- the concept of halves,
- comparing and ordering whole numbers.
Exclusions
Students will not cover
- approximating the areas of shapes,
- reading or writing decimal, fractional, or mixed numbers,
- identifying polygons,
- multiplying to find areas of shapes.
