Math practice app for kids. Multiplication, division, addition, subtraction with single digit numbers. Game Motivation - after practice kids can play a round of casual game as a reward.

Adaptive Tasks - number combinations which caused problems (wrong answer) will be repeated more often so your child will improve in solving these problems faster.
