Doing perimeters brings back so many warm memories of when I was learning math in school. It was such a long, long time ago but I still remember how to do it. Your first video was adorable with the boy learning from his coach how to swim the perimeter and measure it. I'm sure kids will definitely remember the perimeter. The second one was also good because I like this teacher. He explains really well. You always do such a good job finding these videos.

Have a great week ahead! I hope you are doing well. Please take care!
