Topic 12 Envision Math --- Students will manipulate and test 3D shapes for three attributes: Roll, slide, and stack.
I had students play this as a game in groups. I ended the lesson with a challenge to make a stackable unit with all four shapes. It was hilarious. The one rule that kept students from being rowdy was that if any shape (the sphere being the most likely) fell off of their table, their team would lose 'points'. They loved it and were very considerate of one another so that no shape ever fell to the ground.
