We almost hate to leave our unit on Geometry, because it has been so much fun! Yesterday we made all the shapes with play doh and today we made shapes with toothpicks (edges) and miniature marshmallows (vertices). First we had to decide which 3-D shapes we could actually make. The children decided that they could make a cube, triangular prism and pyramid. After pairs of children made those shapes we challenged them to make a rectangular prism without adding any extra points (marshmallows) but allowed them to break the toothpicks in half. You would be amazed at how many of the children figured it out!
