It is often difficult and frustrating for children when they solve a long multiplication problem when they realise somewhere along the way they have miscalculated and therefore got the wrong answer.
Grid Guru supports children through every step of the grid method by checking every calculation the children solve. The children can choose from a range of calculations such as TUxU TUxTU HTUxU or HTUxTU or even choose their own numbers.
The app then displays the calculation in the grid method. Children can then press the partition button which then partitions the numbers into the correct grid. It would be great if children could input this themselves rather than having it done for them. However by asking the children to discussing and writing how to partition the numbers they could then check their answers against the app.
