Good, but not grea; please lose the step count...
The concept and, for the most part, the execution, is pretty good. However, math fluency requires numeracy, which is the understanding that there are multiple ways to get to the same place. This app counts the number of steps needed to solve each problem "perfectly", when in fact alternate solutions are perfectly fine. I wont be using this with my students because I dont want them to fall into the traditional textbook trap of, "Theres only one way to do this…." And, by the way, I solved a couple of the problems in significantly fewer steps than given, so the count is misleading anyway. Id probably have given the app four or five stars if solving the problem in more than the designated number of steps didnt make it look as if the problem wasnt solved correctly.
