Was it great? Maybe. A lot of kids enjoyed trying to find the surface area of the cylinders I had brought to class. Some of them just like cutting them up. Next time, I want to have cylinders for every student. Guess I better start eating Pringles now.
For surface area of a sphere, I did this activity. I think the students enjoyed this activity more than the previous cylinder one. It was very interesting and I recommend trying it in your classroom!
