Comparing Areas and Perimeters (B) WORKSHEET

Suitable for Grades: 3rd Grade
CCSS: 3.MD.D.8
CCSS Description: Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

Comparing Areas and Perimeters (B) WORKSHEET DESCRIPTION

This series of differentiated worksheets enables students to recognise that shapes with the same areas can have different perimeters and vice versa. In this version students will consider rectangles with the same area and discover that they do not have the same perimeter. This includes learners using their knowledge of factors to draw rectangles with a certain area on a square grid.

All worksheets are created by the team of experienced teachers at Cazoom Math.

Frequently Asked Questions

This concept helps students develop a deeper understanding of how area and perimeter are independent measurements that don't always change together. When 3rd graders work with rectangles that share the same area but have varying perimeters, they begin to see that mathematical relationships aren't always straightforward. This foundational understanding will serve them well as they encounter more complex geometry concepts in later grades.
