App Profile: I See Addition and Subtraction

Addition and subtraction calculations are made visual by I See Maths + -. It allows educators to create a range of images that help children to understand key calculation concepts.

The Singapore Bar feature allows the 'part-part-whole' structure to be made visible; calculations can be shown on 10-frames and the 100-square; column + and - can be modelled step-by-step. The images can also be adapted to create meaningful questions. This makes I See Maths + - an invaluable teaching tool.
