Area

What is the area? Because there is only one problem here with a detailed explanation below, consider projecting this as an all-class warm up. Learners examine a rectangle split into 12 squares. They know that each unit is three...

Get third graders excited to work find area and perimeter of unit squares, rectangles, and irregular shapes. A 36-page packet comes with task cards, graphic organizers, practice worksheets, printables with squares, exit tickets, and word...

Given a rectangle with specified dimensions, third graders are prompted to create a new rectangle with the same area, but a different perimeter. This challenges learners to think about perimeter and area in a new way. Use worksheet as a...

Using just the measurements of ten rectangles, scholars match them to their calculated areas. Each of these is measured in feet, so the areas are labeled with square feet. The lengths and widths here are double and triple-digit whole...

Third graders measure area by counting unit squares inside a rectangle.

This is the first of a series of four lessons designed to examine and understand the concept of area. A review of area starts the lesson, along with a discussion of different attributes that can describe a rectangle. The term square unit...

Find the area of squares and rectangles and discuss square inches and square centimeters with your young geometers. Follow the example provided, and then let learners try it for themselves! They will find the area of seven rectangles. 

Gardening geometers construct the formula for the area of a rectangle by viewing a video revolving around two young people, their lawn mowing business, and their need to charge by the square meter. A relevant real-life application lesson!

Third graders determine the perimeter of a shaded section by counting the number of unit squares that surround it. Each section is shaded on a small square unit grid.
