Numerosity: Play with Subtraction!

Numerosity: Play with Subtraction! has received the Teachers With Apps Certified badge*!

Aimed at 6 to 8 year olds this educational math game motivates kids to discover the rules of Subtraction through play and experimentation. Have fun learning Subtraction by playing with numbers and progressing at your own pace.

Numerosity encourages kids to use their imagination while learning maths, by moving numbers around, observing the results of their actions on the screen and learning from the immediate feedback.

Children’s progress is visualised in Numerosity not only by the number of points and coins they are winning, but also by the ‘color-code’ in all the levels, starting with Red = ‘Need to improve’, going through Orange = ‘Not too bad’, Yellow = ‘Good’ and finally, Green = ‘Fantastic!’

In Subtraction, kids are joining Skruff on a galactic trip, creating profiles to challenge friends, winning coins, unlocking all the 20 levels, trying to beat records and winning the most challenging achievements to become a master of Subtraction!

And, at the end of the game…SURPRISE! A fabulous certificate* to show off and say: I’m a Subtraction Superhero!!

Praise for Numerosity:

**Featured in ‘App Store Best of 2012’: Numerosity**
