I have no objection to a limited amount of well thought out flexible HW, that accepts all children are different.
Reading and tables are necessary, but please don't insist they read every single night or that Mum puts a comment in a stupid book.
I had the worst and best readers in the class.
There are only so many ways you can write "just as bad" or "just as brilliant" as last night and the night before.
Especial as neither child is stupid and they were well aware Mum was writing rubbish.
HW that shows what they are learning in class is nice occasionally, but bringing books home would be better.
Senior school HW that is practice maths or write an English Essay in peace I didn't mind.
Research history, geog or science is fine if the amount is sensible, there is sufficient time and the guidelines are clear
Posters, leaflets, copying the text book and the sort of primary projects that are clearly just work for parents are pointless.
And please never ever set any HW for Tomorrow, on Friday for Monday, Whether over a weekend or half term.
Sorry school can take over family life for GCSEs etc., but it shouldn't the rest of the time. Six hours a day, 191 days a year is quite enough.
I got lots of finishing off HW because some of my teachers let our classed misbehave. I resented it mightily and very rarely did it. Made no difference to my results.
