My DD is 7 and I would describe her as average at all her school work. She has quite a lot of HW each week which she does with a bit of prompting and moaning.
She has little interest in on-line games, DS etc and I have never bothered with any of the on-line educational sites as I think she has enough already.
But then I come on MN and there are posts about all these extra curriculum work that can be done on all these sites, some free, some to sign up for.
Is there really any advantage for a young child in these? I can see for a teenager perhaps, then I worry that everyone else's child is doing more work and mine will get left behind!
