Measure each side and add them up! Here is the video with the perimeter song that we watched in class! Feel free to watch it again! 

 Here are some ways we can use perimeter outside of Math class:

1) fencing in a backyard

2) creating a garden

3) putting a pool in the backyard

Can you think of any other ways to use perimeter outside of Math class?
