"My son struggles with writing, forming numbers, and putting them onto paper. He struggles to write numbers underneath each other in correct columns, even though he knows exactly which column they belong in. This has led to a struggle with completing sums, even though I know he can do them. Now that he can do them on the screen and type the number in, he is flying. This is brilliant for him and for me (his mum), thank you so much for this!"
