Preparation: Copy one handout for each student and then cut the page in half.
In this activity, the teacher creates 10 different shapes with electrical tape on the floor. The goal is to have a variety of sizes and number of sides so the calculations are different. Number each shape with a sticky note 1-10.
The students then use rulers to measure the sides of the shapes and calculate the perimeter. The student records the perimeter on the top piece of the worksheet. It is up to the teacher how simple or how difficult the shapes should be.
This activity works well when the students work in partners. Allow the students anywhere from 2-4 minutes to complete each shape, then each pair rotates to the next station.
Practicing perimeter in this manner is idea for addressing multiple learning styles because it allows the students to work socially and move their bodies while learning important math skills.
After all calculations are complete, hand out the perimeter challenge portion on the handout. This is a great Exit Ticket or quick assessment tool.
Bonus: You can leave the regular (not irregular) shapes on the floor and do the same activity with area as well!
Have fun learning! Sincerely, MsWall4
