Bottom Line: First, let me provide full disclosure and admit that I am especially partial to any app that allows me to control a character named Mister Chickenpants.
For example, the player will roll under 15-5= with boxes for 10, 11, 12 and 13 underneath.
Children can chose one of the following characters: Hula Girl Grape, Orange Boy Wonder, Princess Pinkberry, Captain von Blueberry and Mister Chickenpants. It doesn't get much better than that.
The movements get much harder than just tilting slightly left. There are mountains to climb up and roll down, a giant ladder to climb and masked, red-ball meanies to jump over.
One of the things I liked is that the timer in the game only gives bonus points. If the player is having trouble with a problem or movement, they can actually bring their Bumpie to a stop or slow roll, think about what they need to do, and then proceed. I don't like children's learning apps that have a "times up!" feature, unless it can be toggled on and off.
At the end of each level, the app presents total points (calculated by solving the most problems in the least attempts and least time), gold coins earned, problems tried, how long they played and what percentage they got on the first try. It also saves their high score for each level.
Another good sign: I generally have to turn the background music off when reviewing a kids' app after a minute or two, but the music in Math Bumpies had me moving around a little bit in my chair (not a pretty picture) instead of turning it off.
