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!
