This project is a great way to see what students understand without asking them to write an essay or give a presentation. The dodecahedron has 12 sides and, when complete, will form an actual three-dimensional figure. Each side of the dodecahedron represents a different concept. For example, the instructions in this document stipulate that students should create 1 side as the title, 3 sides for vocabulary, 3 sides for characters, 3 sides for important story events, and 2 sides of free choice.
The great thing about this project is that it can be adapted across subjects. It would make a great social studies or science review, or a new way to remember math concepts. I used it as a book review and that is what the instructions here are for! There is also a checklist so that students may review what they have completed and check it off as they finish each side. I found that this helped my students who struggle with organization.
Also, this would make a great group project or can be cut in half (only use 6 sides) to simplify down for younger learners.
