Math Rider is a math facts games that you can download to your computer. It is a complete download so you can access it without internet access once you have the program.
A 'game' that really is reinforcing the basic math facts of addition, subtraction, multiplication and division. The game is designed for children ages 6-12, but I personally found it fun to see how much I knew and remembered! You really can personalize it to what ever age you need to work with. The graphics and storyline however work best with this elementary aged group of kids.
You can get a full 7 day trial of the game simply by submitting your email and they will send you a registration code. This would really be worth it if you think it is a game your child would enjoy, just to test it out. I love when they allow that for parents to see if it is what they are looking for.
The Math Rider sells for $47 for a lifetime of updates. This allows for 8 players.
