I found this idea on Pinterest and just had to do this with my class when our Geometry unit came up.

It is a simple activity but very effective.
What you need: A lot of mini marshmallows and A LOT of toothpicks

I gave each group a few sample shapes and off they went to create their own 3D models.

I liked this activity because it forced the children to think about the edges and vertices of each shape while trying to recreate them.


  1. I love doing this. When I taught 1st, it was part of the math curriculum...only you had to use gum drops. Then you dipped the shape into water. When you pulled the shape out you could see the shape faces in addition to the edges and vertices. Very cool.

    1. What a great idea! I'll have to try that next year. Thanks for sharing that. :)

  2. Great creation and I appreciate that, geometry is most interesting and in just play student can get the concept.
