I don't think homework as such is wrong, I think the sitting down at a table quietly type for a 7 yr old is.
We do lots of educational type things, nature hunts, reading the football results, top trumps, sorting change in shops, playing adding the numberplates on car journeys. We went to a castle and pretended to be tudors for dds tudor topic (for her that was more exciting than producing a poster that, to quote the link, "The thing I detest the most is long-term projects," says Hattie. In many cases, "all you're measuring is the parent's skills").
I guess that all homework is really about the parents skills and I'm just not that skilled at getting mine to write paragraphs on a reading book and yes, that's probably because I just don't think it's that important.
What I do get from this thread is that, like religion and politics and if dc should be invited to weddings, it's something that people have an opinion on and no matter what's said that opinion won't change.
