Bottom line: A fabulous math app for your special needs or young elementary-aged child. Since we first reviewed ToDo K-2 Math Practice, it has evolved to an app with a new name and even more math. The new ToDo Math is built on the same basic premise with math activities that can be completed in two different ways. Replacing the original timed math practice, there are now Missions for users to complete. Or, children can engage in free choice which allows them to select math activities as they wish.
