NEW Perimeter Math Resources for 3rd Grade


We have launched our perimeter math resources, specifically designed for third grade Common Core students.

Students are introduced to perimeter by fencing in a space to hold animals. As they outline animal pens with fencing, students develop a conceptual understanding of the equations that can be used to find perimeter. They then use what they’ve learned to create one or more rectangular pens with a given perimeter.

1. Create Perimeters: Understand how to make rectangles with a given perimeter and that different shapes can have the same perimeter. A suggested method is to make the width and length add up to half of the perimeter.

2. Fancy Fencing: Practice creating rectangles with a given perimeter and different shapes with the same perimeter.
