This could be a good game, but it needs to change the answer choices. Every choice is one less than the correct answer, the correct answer, and one more than the correct answer in mixed up order. If you just select whichever number is in the middle of them if you put the in order, you will get 100 percent correct without ever having to even look at the math fact. Fix the answer choices to be more random and it will be much more useful as an educational tool.
