I know we are all trying not to use Styrofoam these days but occasionally it can’t be avoided. So when I spotted this great math teaching tool made from them I thought that it looked like a great way to keep some from going in the landfill. Pop on over to the blog Planning Play Time for the tutorial on how to make a recycled styrofoam cup math teaching tool. I bet this could also make a fun puzzle if you colored a pattern and then had to spin it to get the design back.
