Super Games is a excellent iPad app for educational games from the famous educator Mr. Nussbaum. These games are designed for grades K-8th and cover a wide range of subjects such as: Math, Reading, History, Geography, and much more. There are over a dozen of free games to choose from and you can unlock all 40 of them for $1.99 (although free today).
