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...

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...

Given measurement information on individual squares within a larger shape, scholars determine the total area of that square or rectangle. For one of these three problems they draw the shape knowing its total area and the measurements of...

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

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...

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. 

If shapes have the same area, do they always have the same perimeter? Learners explore the relationship between the area of square units and their perimeters in a hands-on activity. Observations are recorded, and they begin to recognize...
