"Animated Arithmetic CD" for Windows and Win 95

teaches addition, subtraction, multiplication and division for children
from 1st through 4th grades.   

It provides exercises in addition and  subtraction with and without 
regrouping.  Problems can involve up to 9 digits.  More than just a 
drill program, progressive  help is given as needed to instruct the 
child to solve the problems.

The multiplication and division problems are based on the multiplication 
table from 1 to 10, it teaches "mental math" in a painless way.  
Progressive help is given as needed when the student is having difficulty 
with a particular problem (not just a Wrong! response from the computer). 

Once ten problems are completed,  the student gets to visit the game room.
There are puzzles with animation and sound, and a maze game where the child
can make their own mazes (which are rewarded with an animation when solved),
or make their own mazes.
