A variety of simple math fact review activities including facts against a timer, building a number sentence and 11 different "math square" games. Many timed activities are accompanied by a "Hall of Fame."
We wrote this facts review program to eliminate some problems associated with paper work sheets. There is no copy machine, no hand correcting, and for students that have trouble with the pressure of timed tests, most of these puzzles allow them to practice independently with a timer. Best of all, these activities are perhaps a bit more fun than regular paper worksheets.
And what could be more fun that running an Aqua-style interface on a non-OSX PPC or Windows machine? Need to run your iMac lab under OS9 with only 256 colors? Hey, us, too. Specially optimized graphics insure that Aqua-style color gradients look good even at 256 colors.
Although many of the games in this application were designed with 8-10 year olds as the target audience, most ages from 7 and up will find suitable activities.
