We created pyramids and prisms using marshmallows as vertices and toothpicks and stirrers as edges.  This is a great hands-on activity to discover the parts of geometric solids. We also discovered that shapes constructed of squares and rectangles are much weaker than those made from triangles (a little physics lesson).

Looking for a fun indoor activity? Give your child a bag of marshmallows and a box of toothpicks and watch their creativity!
