After my last post, Mike Lawler gave me all of these awesome ideas for my 3D geometry class. Considering that my class has been working on nets, I was most fascinated by the dodecahedron that folds into a cube, which came from Simon Gregg.
When I first watched the gif animation, I just couldn’t figure out what was going on. I thought, “I’ve got to show this to my students!” Thursday was that day. I tasked them with a build challenge. Of course 55 minutes wasn’t enough time to complete anything, but students had drawings (which gave us insight into the construction)
a CAD rendering (completed during a snow day)
and a previously constructed dodecahedron that had been re-purposed (completed during lunch).
So, thanks Mike, for the inspiration, and thanks #MTBoS for being there helping us to support each other.
