And not only is it goof-off day, being the fifth Thursday of the month, but it's time for that occasional part of this blog -- the arithmetic. FUN arithmetic! Looking for any children's math games? Family math games? Not all of these games use numbers; some just exercise your logic and spatial relations. Like this game reminiscent of Mario. Tilt the game back and forth using the arrow keys to get the friendly little round guys into the bubble. But they have to hit any coins that appear, and don't let them get eaten by the mean little spiky guys! Have fun, and happy goof-off day.
