These are hanging above my desk right now, and they make me so so so happy.
I use slide-togethers like this as a puzzle for my students, often in a problem-solving class that I teach.
But all but one of these I made myself… They’re just fun!
You can find printable templates for these here. Both this site and the original creator of the puzzle leave the instructions intentionally vague, so I won’t get too specific either – you really do have to just puzzle it out!
A few tips:
- Start (or have your students start) with the hexagon construction. It doesn’t have any tricky corners, and is more stable than the triangles. All the others have three-way corners, which take some getting used to – better to practice constructing a ball shape first. After the hexagons, I suggest trying the squares.
- Print these on cardstock. They can be made out of paper, but don’t hold together as well – plus, they tend to rip. If you use paper, you might need to use a bit of tape too. On cardstock, they support themselves pretty well.
- Look closely at the pictures of constructed spheres! I have my students count how many pieces join together at a corner, how many edges surround a hole, and look at what shapes are formed before they even start – focusing on one element makes it easier to see how it goes together.
