I'm tutoring a boy who is really struggling to learn his times tables. His class teacher is sending home a different one to learn each fortnight, or so, but he is still working on 3s with me. Meanwhile, the 4s and 8s have just 'passed us by'. He is progressing with the 3s, but it all has to be visual activities, as he doesn't retain anything verbal. Do you think we should stick to the 3s, until he's learned these, or do 4s as well? I don't think he'd cope very well with both at the same time. I also suspect dyscalculia.
