MultiBingo

MultiBingo (iPhone, iPad) combines the classic game of Bingo (mark announced numbers on your card and get Bingo) with Math: you must mark a number on the card with a combination of two digits.
CalcGame

Calcgame (iPhone, iPad) is a puzzle with numbers. And it is a great tool for children to have fun (and competition) with math!
You get 4 different digits. With one or more of these digits and possibly one or more of the other calculator buttons you must make the value "1". When you succeed, you go to the next level and must create the value "2", and so on. The goal of the game is to reach the highest possible level with the given digits.

MemoMath (iPad) combines memory skills (remembering where matching cards are located) with Math: two cards match when one card contains a calculation (like 6x7) and the other card contains the corresponding answer (42).
