Simple, easy, levels over too quick

My 3rd grader uses this app as a short warm-up before doing math. He plays it willingly-but he never actually ASKS to play it! I like that the program waits for him to choose an answer instead of having buzzers go off if he takes too long. It is a gentle, positive drill on math facts. If you choose the "hard" setting it is really a nice mental math warmup.
