DS (11, in Y7) has a lot of difficulty remembering stuff from school - especially maths, which he is OK at doing when he can remember, but it needs to be in front of it a lot. Every now and the DH says he will go through it with DS every day, but TBH it's just not realistic either of us could keep that up. I know with ADHD motivation by getting something positive in fairly short order can help, so I'm wondering if I there is a good site where we might be able to set him a certain amount of revision in order to get screen time, for example. Something we could check up on quite easily just to make sure the maths is just kept in front of him in between topics/
