"Motion Math creates movement-based learning games that give players an intuitive sense of math."
"Motion Math: Move, Play, Learn!"
"Motion Math provides a much-needed experience to bring the body more fully into mathematics learning” – Roy Pea, David Jacks Professor of Learning Sciences, Stanford University
Ummm...this is a hand-held game that involves tilting an iPhone. If you go to the site and watch the promotional video, you see kids sitting on couches, staring at little screens. So what if they might get better at fractions? They most likely already get enough screen time. And yet, there they are in the video, sitting on the couch, watching a little ball bounce on the screen while their precious brains are wasting away into cyberspace, or wherever brains go when their bodies aren't moving.
Thus ends my rant.
