Customer Reviews

Loved it enough to buy the iPad version after using the iPhone one!!

Definitely at MUST-Have. Helps your child develop a solid understanding of basic mathematics in a wonderfully engaging and easy to understand manner.

Negative numbers?

Cute, but I don't get why negative numbers are allowed in a little kid app. If it said, " you can't eat 8 fish when you only have two", I would give more stars.
