Stacking Squares

This art activity comes from Lucky To Be In First. Students measure, cut, and paste squares in descending order. Each square is 1/2 an inch smaller than the preceding square. Also check out Spiral Triangles!

Note: You could also have children figure out the area and perimeter of each square on a separate sheet of paper.
Example
1. area = 25, perimeter = 20
2. area = 20.25, perimeter = 18
3. area = 16, perimeter = 16
4. area = 12.25, perimeter = 14
5. area = 9, perimeter = 12
6. area = 6.25, perimeter = 10
7. area = 4, perimeter = 8
8. area = 2.25, perimeter = 6
9. area = 1, perimeter = 4
