Now think about students in grades 6-8 and how this Platonic solids activity might work with them. What must students know and be comfortable with to get the most out of this activity? What are potential stumbling blocks for them?
I think that this lesson would be a good fit for 6th-8th graders. I would recommend purchasing the pieces that were used in the video. I cut all the pieces out and then taped the regular polygons together. This proved to be quite a choir. I tended to spend more time thinking about how many polygons I needed to cut than the purpose of the activity.
Students should be comfortable with some basic definitions for this lesson. Students should have a basic understanding of vertex, regular polygon, platonic solid, edge, side, angle, and face. A potential stumbling block would be the task of cutting out all the shapes. Reasoning why there are only 5 platonic solids would be the main stumbling block for some students. The doing part of the activity is not difficult, but the reflecting on what you did and why that happened is a difficult thing for many to do.
