Many of the games can be played on an iPad or computer.
Drag n Drop Math is great for practicing both the traditional and partial product method for multiplication.
Ultimate Speed Math and World Cup Math would be a great game to start practicing your division facts. You could also practice your multiplication facts.
Also, Ameriquake and Conquer the States are great games for practicing the fifty states. I know a lot of the kids are trying to get into the Fifty Nifty Club and many were very close last week.
