Great app
My kids love this app. Really nice concept for practicing math.
Math practice without pain
My 2nd grader enjoys this and it gives her a way to practice subtraction that is nonthreatening and fun. She loves watching the outline develop and swiping off the gray picture to reveal the picture below. Yes, she could click on the answers until she hit the right one without really thinking about it, so this game is probably best for kids who understand the concepts of addition and subtraction and need to practice their math facts rather than those who are learning addition and subtraction.

Kids like it, but...
The design of this app is rather amateurish, and the in-app purchasing is a super-hassle. It often forgets that you have unlocked it, forcing you to disable restrictions, turn on in-app purchasing, then confirming your blasted password over and over. There is no good place for the "restore purchases" option either. You have to delete the app, then reinstall and go back into puzzles to restore.

Dino Drills-
this app is a good drill activity for students to practice their subtraction. as an education major, i liked the option to change the difficulty for each user. one thing that i would say would not work in the classroom, is the fact that students can avoid doing the math problems by sampling clicking on answers until they selected the correct one to get to the end coloring portion.
