...'Littentree my 9 year old goes to a very academic independent school and has no homework at all! And that's the way it ought to be as she has an awfully long day and Saturday school'.........
You've got it, in 'awfully long school day'. Your DC are no doubt actually being taught from 8.30am to say 4.30pm.

Oddly enough, although the above describes the school I went to, it couldn't be further from the primary DD went to, where they also had very little homework - that school had kids in it who didn't even get fed properly at home let alone have someone capapble of supervising homework.
Though for completely different reasons, they also took the line that any significant learning would be done at school - and it worked out fine for DD who didn't have her primary school years blighted by pointless homework, and moved quite easily to a reasonably academic secondary school & organising her homework there.
Though if I've understood, I think your beef is more to do with inconsistent homework at secondary level? And I probably agree with you on some of that.
And while I'm really glad that our primary set much less than the guidelines (most importantly didn't have weeknight homeworks), I am all for things like reading with children being encouraged in the early years, and independent projects in the later years of primary school. Things like open-ended projects which can really stretch the ones who were ready for it.
And I read something recently about teachers looking for signs of neglect in young children - parents never signing the reading diary was one of the ones mentioned (obv. in the context of other things like children turning up hungry & unwashed etc.) - so there's definitely value to the home / school relationship being monitored a bit.
But generally, I feel quite lucky that her progress didn't depend on us being to fit in half an hour of homework every night through primary school, because we really would never have managed it.
