First, let’s begin with some basic vocabulary….
Tetrahedron – a pyramid with four faces that are all triangles
Square-based pyramid – a pyramid with four triangular faces and one square face (The pyramids in Eqypt are square-based pyramids.)
Cube – a three dimensional shape with 6 equal square faces
These 3D forms are fun and easy to make…. here’s all you do:
1. Form equal size balls of Model Magic, about the size of large peas.
2. Stick toothpicks into your Model Magic to form the basic shapes of a tetrahedron, a square-based pyramid, and a cube.
3. Now, make another cube. Use four more toothpicks on each face of your cube to form new square-based pyramids. When you’ve done this on each face you will have made a 3D star!
I love this! I think we will have to try it.
we have done this a lot here we have used marshmellows in place of clay and it works great. we have also done this as team building trying to build the tallest structure togehter.
What grade level would you do this with?
This lesson is perfect for grades 3 and up, but younger kids can do it, too, with a little help.
