I'll put in a plug for maths club. It's really not that hard to set up. And it's huge fun! Keep numbers small; group by ability not age; and have lots of varied activities. I find a circuit-type set up works well so there's 5+ activities and you get some mastery by repetition without being drilled and having to go over and over things. There are lots of online websites to help for interesting activities. But just finding top 10 ways to learn timestables can be good fun and really useful. Always room for some worksheets if you're not feeling terribly creative. And lots of parents are willing to help... jojo
