Two ideas:
1). Build models of the 5 regular solids and show
why these are the only regular solids. Also
show some of their properties.
2. Why not explore the 3x+1 problem? It is
so easy to demonstrate, but no one can prove it!
There are many websites on this topic.

Make a dodecahedron ( a solid with 20 regular faces of pentagons.). Easy, quick and cheap. I did the same.

Better do Trigonometry or Algebra.
