Great for a kid that reads but a bit more difficult for K-1st graders.  Works great for the younger kids if an adult or older sibling can help in between quizzes and to get it started. The screen can be hard to see but its nice to have a dedicated math game that can't be switched out to angry birds :). I know my son is practicing if he has this in hand.  Wish they would fix the screen or allow for voice prompting, but it does exactly what it says in the description-quizzes math facts.
