[Channel-talkgeometry] Lesson 10 - question B5

From: Debra Schneider <19debbie19@sbcglobal.net>

Here is my response, please post it.

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 actually think that the Platonic solids is a great activity for my 7th and 8th graders. I believe that if they actually cut out the shapes like I had to do because I didn’t have the set of shapes as in the video that manipulating and taping the polygons together will make the concept clearer. I do think that the students should work in groups of four, so that they can discuss what is happening and that it will take less time in building the solids. What wasn’t clear to me was that the polygons around a vertex was the unit by which you made the platonic solid. The solid could be made up of more than one unit, but for every vertex of the solid there would be that many polygons around it. I would “walk” my students through 3 and 4 triangles around the vertex before letting them work alone.
