How I Use It
Only as reward/free choice time. The students don't often choose the more challenging games and opt for the goofier, flashier, noisier games unless prompted to do so.
There are lots of great math games but my experience is that students choose games that are more a game experience than a math experience. Many choose to play the Run game, they control a player that runs on blocks, or Bloon's Tower Defense, students watch balloons pop, rather than other great math games that would increase their math skills and knowledge.
