One of my favorite summary activities this year was creating a octahedron with students throughout our 3-dimensional measurement unit (CMP Covering and Surrounding). A year ago I found this pin on Pinterest.
When I saw this picture I visualized each face having an important vocabulary word or idea. Since I am not big on students memorizing formulas I thought I could use the summary questions to help students explain HOW to find volume and surface area of 3-d figures in words.
I posted the questions on the board at the end of each investigation.
Students were given two paper plates and wrote their explanations on the triangle formed by folding the edges. I made sure they all wrote on the side with edges facing up so we could easily staple the flaps together. I am sure you could do it on the other side but I didn't want to spend too much time figuring out how to get the staples to all be on the inside.
As went discovered new ideas our octahedron started to form. I only did 4 out of the 5 investigations so it ended up working out perfectly to have 2 questions per investigation.
I allowed students to use their octahedron on the test as a "cheat sheet". Unfortunately many students didn't really think about the benefit of having complete and correct answers on each triangle until the day before the test.
This was a great activity with the students and most students were engaged throughout the process. In the future I would like to possibly hang them from the ceiling after the test!
