SUM! – iPad App

Plus? Minus? Equal? Just feel them before going math!

When teaching someone to calculate for the first time, numbers can often be represented by a shape, like a circle. Use of shapes allows for a visual understanding of the concept, since the quantity of shapes increases when added, and reduces when subtracted. SUM! is an app that teaches the concept of addition and subtraction in a similar manner through play. Moreover, it is fun as a simple game. In the app, the nature of the numbers is represented as the personality of the characters. Just as each child has a unique individuality, each number has a unique face and personality. It’s an app for not just kids, but everyone, to enjoy adding and subtracting to build familiarity with numbers.
