The Counting Kingdom is an excellent iOS game for kids 6-8 yrs old looking to work on their addition skills. The game works like a "typical" defense game and has kids adding numbers together to cast spells and defeat their enemies. This is a perfect way to integrate technology into the classroom using Game Based Learning. There are over 30 levels, gets harder as the game progress, and has lots of replay value.
