Ontario Curriculum Expectation:

3.E2.1 use appropriate units of length to estimate, measure, and compare the perimeters of polygons and curved shapes, and construct polygons with a given perimeter.


The perimeter of a figure is the total distance around the shape.

We use unit grids to find the perimeter of any figure. Each square is 1 unit by 1 unit.
