Activity Instructions

Place a beanbag on a number in the middle of the mat. For example, 48. This is the area of the rectangle students will make. Use painter’s tape to make a square with corners at 48, 6, x, and 8. Then, have students determine the perimeter. In this case, two sides have the length of eight and two sides would have the length of six, thus making the perimeter 28. Have students find another rectangle on the mat with the same perimeter, but different dimensions, or the same area with a different perimeter, etc.
