This math facts app has good some good classroom features lurking beneath it's less than polished interface. That's because it was designed by a teacher -- John Crandall.

Your objective is to help your avatar climb a wall by accurately answering math fact questions, presented as multiple-choice problems.

Correct answers mean faster climbs and more coins (note there are no IAP). Perfect scores a special dance, and eventually entrance to the five star club. You can send progress reports for correct answers and number of problems attempted, for each grade and level.
