Lesson Plan: Area of Squares and Rectangles Mathematics • 4th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use a formula to calculate the area of squares and rectangles.
Students will be able to
- state the formula for the area of a rectangle as length width = area, or base height = area,
- state the formula for the area of a square as side length side length = area, or base height = area,
- multiply to find the areas of squares and rectangles,
- compare the areas of squares and rectangles,
- find missing side lengths by finding missing factors,
- investigate how many ways there are to make a rectangle with a given area.
Students should already be familiar with
- counting unit squares to find the area of rectilinear shapes,
- finding the perimeter of squares and rectangles,
- multiplying whole numbers up to 2 digits by 1-digit numbers,
- multiplication tables up to .
Students will not cover
- square numbers and exponents,
- converting between units,
