I run a maths intervention and use Singapore bar models and Base 10, which really help the children see the calculations. I'll be able to use is with larger groups as well as introduce it to teachers throughout the school. I'd like to see an option to step back through calculations and the ability to always hide answers before you work through the question.
A maths app that pictorially shows in real time how numbers add on or subtract. Subitising to improve manipulation and number bond knowledge. Singapore bar to look at visual values, base 10 to show those 5 and 10s clearly, htu to show carrying across visually... It's a superb teaching and learning tool. The children who get to use and see this app are privileged.
