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.
We've made a couple of refinements as teachers begin to use the app in the classroom:
1. We've changed the term 'Units' to 'Ones' to marry up with the new curriculum requirements;
2. On the Singapore Bar, if the numbers had too large a difference, it could result in one of the numbers being unreadable. We've sorted that... Well actually, Doug, our amazing developer sorted it! But he is good like that!!
With Family Sharing set up, up to six family members can use this app.
