Welcome to another weekly puzzle!
The ‘football’ shape in the puzzle is called a truncated icosahedron. If you’ve been working on any of the origami from this blog you might have built shapes similar to this.
After you’ve done the puzzle, you might like to read about icosahedra and truncated icosahedra on Wikipedia.
There are interesting problems involving tessellations and 3D shapes here and here. You should try them!
Finally, a bonus puzzle for you this week from another blog. Have fun!
