We started giving DS-then-turning-5 "sum sheets" - on his request, to his specification of number and type of sums and difficulty level - on the day he came home from school complaining about maths being boring (it was counting and number recognition skills!). That was enough for a while; then we started him on ALEKS a few months later. Towards the end of the year we had a good meeting with school and got proper differentiation sorted out for him. I was posting here at the time, so the old threads are all there if you want the details!
