Surface Area

We recently learned about surface area. For some reason, this is always a hard concept for students, and then add in some funky formulas on the formula chart and it totally throws them for another loop. I prefer just to teach them how to find the area of each side and add them together.

I like to start lessons with a brainpop video or youtube video/song. Sometimes you get some good ones, other times they are a little cheesy, but still memorable, like this one:

I thought it might be fun to do something different than just drawing a picture of the sides. We pulled out some paint and 3-dimensional shapes and stamped the sides instead!

When the posters dried (we used a hair dryer borrowed from the nurse), we started measuring and calculating!

  1. I love this idea so much! Surface area really throws kids off. I will definitely be using this in my class!
