3D marshmallow models

Monday, April 7, 2014

What better way to understand faces, edges, and vertices than by building them yourself? Today we used toothpicks and mini-marshmallows to make:

rectangular prism
triangular prism
square pyramid
hexagonal pyramid
triangular pyramid

The kids had a blast (especially when I finally let them eat!) and were able to grasp the concept of vertices and edges.
