A fun game that has no math in it whatsoever. You can play it when your teachers says "Play somethingeducational." That's your cue to play Cool Math Games.
A website that (usually bored students) used to play free games. It is also the death of schools and teachers.
"Bro, I just finished grinding this game on cool math games; I completely missed whatever Mrs. Williams just said."
"I think it was something about decomposers. I was playing Cool Math too."
