I love this Geometric Shapes chart shared by Kathryn on Kindergarten Kindergarten! I had to scroll down to find it, but found a ton of great ideas along the way. I also loved her shape museum. (She has lots of free ideas for teaching math concepts.
This shapes chart would be great to display in your classroom when you are teaching these shapes! This way your students wouldn't have to ask you how many sides a pentagon has.they can just look at the chart!
