Everybody is posting end of the year stuff, so I’ll throw in my favorite math project. A dodecahedron memory ornament. A what? Ha ha.
A dodecahedron is a 12-sided geometric ball (or “geo ball”, as my friend Laurie calls it). Copy two sheets of the pattern for each student on white cardstock. Ordinary paper is too flimsy. Kiddos decorate all of the pentagons before cutting them out. You can give them a theme, or just have them draw or write special memories of the year.
Each student makes their own ornament, but I also have the kids decorate pentagons that I put together into my own memory dodecahedron, which you see pictured. You can either fold the flaps in or out. As you can see from the picture, I like them out. I think it’s also easier for the kids.

You are so welcome. Like I said, it’s long been a favorite of mine!
I like this! I think I will be making these with my second graders!
I’m sure they will love it!
This could be the perfect little side trip for testing week! What a fun way to learn a little math AND save have something to remember our year.
Absolutely! It’s always a crowd pleaser. 🙂
this looks like a fun activity. thanks for sharing.
This will be a great addition to my 4th grade unit on The Phantom Tollbooth- which if you haven’t read it in a long time or ever, has a character named the dodecahedron! Thanks for sharing.
I loved that book when I was young, but didn’t remember that particular detail. Thanks for sharing the connection!
