MaTris lets your child practice basic arithmetic. Exercises include counting symbols, addition, subtraction, division, and multiplication. A wizard lets you adjust the duration and content of each session, and it lets you set up a log file to track results. As each question is answered correctly, a spider drops down a wall. When it reaches the bottom, the player is rewarded with a Tetris-style game. MaTris has friendly graphics and fun sounds; is easy to use; and comes with English, German, Italian and Swedish interfaces.Requires the VB 6.0 Runtimes.
