Calling all families, communities and schools! We want you to build a tree, with a mathematical twist! Discover how to build a tetrahedron from a net, then join 4 (or more!) tetrahedrons to make a Sierpinski tetrahedron. We call these TetraTREEdrons!
Materials you will need
- Tetrahedron Template (available to download below)
- Plain paper, pencil and ruler
- Colouring pens, pencils or crayons
