The app allows children to practice their maths skills for addition and subtraction from 1-20. It includes increasing difficulties to encourage competitiveness, as well as picture helps for those days when they are just not feeling in-the-mood.
Images, animations and music help increase the fun atmosphere whilst they get a grip on their numbers.
Instead of reading a lot more waffle, why not give it a try? The first 45 levels are free. Then you can upgrade to the full version with 180 levels.
