Yestereday we played the game FLUXX in my high school Geometry classes. I randomly placed students in groups of 3 or 4. My purpose wasn't to teach any Geometry content standards but it definitely should have made them think! The students recognized that the order in which they played their cards made a difference on their possibility to win. Hmm...the order in which they solve a right triangles matters too! I guess it will help to teach trigonometry this coming week!
Everything I ever ask my students to do has a purpose. But that purpose can change after the fact. The original purpose of the game was to give my students time to relax and de-stress. But after student comments about the order cards are played being important, my purpose has changed.
