Dodecahedron craftivity

Are you looking for a fun end-of-year project? Or a creative way for students to reflect on a math unit? Enter the dodecahedron!

A dodecahedron is a 12-sided geometric ball. There’s a little bit of cutting and pasting involved with this craftivity, but the result is a true keepsake.

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.

After cutting out each of the twelve circles, students fold the flaps up toward the decorated side along the dotted lines. They then carefully glue the flaps together to form the dodecahedron. Warn them in advance that this project requires precision! The neater they cut, fold, and glue the pentagon sides, the better the overall project will look.

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.  .

There are lots of different ways this project could be used. I have used it at the end of a unit as a review. For example, at the end of a fractions unit, students could decorate all of the sides with things they’ve learned about fractions. The dodecahedron, of course, also makes a great holiday ornament.

Have fun!

  1. 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.

  2. 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.

    1. I loved that book when I was young, but didn’t remember that particular detail. Thanks for sharing the connection!
