"I've started a list of educational iPad game apps for parents. I've got a special affinity for these games as I originally started my career in technology as a first generation educational software designer. The list contains casual, fun games to use at home. They don't necessarily help you master long division or prepare for an upcoming geography test. The accent is primarily on having fun. If your child isn't going to enjoy playing then the app won't make the list. The second important criterion is that time spent playing is productive and that something of value is learned while playing the game."
