How much involvement do you have in 12 year old’s homework?

I help if they ask for help, but otherwise leave them to it.

At some point your child needs to learn to work independently, so IMO if you're helping your child now, it should be with the aim of reducing it over time, so they can do it themselves.

A thought for the poor assessments - does he understand how to revise? This isn't a skill either of my DC were ever taught and not one they may have needed prior to secondary school.

Practical help...
Ink and paper in the printer. Fully stocked pencil case with regular top ups. Supplies of A4 Pukka Pads - hard covers keep paper neat until it gets put into files. Ring binder files for each subject. A clear part of the kitchen table and (relative) peace and quiet.

Organisational help...
Timetable and homework timetable printed out and stuck up on the fridge. Shelf in kitchen set aside for books + files. Laptop + internet access for 12 year old to use.

Time management help...
Expectation that we all (me, DH, both DC) work/read/draw/knit/cook/do the crossword from 6-7 and 7.30-8ish. Check in each evening with homework timetable and school intranet (where homework is posted).

I don't actively 'help' with homework, as the teacher needs to see if they haven't understood, but I suggest the use of Bitesize etc if they hit a problem.

I’ve said he now knows where he needs to work harder for the next assessments and if he gets to the end of a class not understanding something then he has to make a point of asking the teacher either right then or at the start of next class.

This will help him more than having a parent sitting there watching him doing his homework.

'too big'

Totally agree about bigger projects/pieces of work. My DS just goes into panic mode when the task feels to big and procrastinates, so helping him learn how to break it down into smaller achievable tasks is very important.

Depends on the child and their needs.

DS1 (dyspraxic traits): Helped with organisational skills and revision techniques for exams until Y11

DS2 (ASD, ADHD): Helped with presentation skills until Y9

DD (dyspraxic traits, language delay): Helped with organisational skills until Y7, still helping her with MFL in Y9.

DS3 (no additional needs): Helped with planning large projects until Y8.

I work in HE and have a son in year 7. I have been supporting him in (a) making sure he understands what he needs to do (b) if it's something difficult for him then asking him ways he could do something or getting him to write a quick plan of what he will include (e.g. a list of features of a cell so he can write about it (c) looking through feedback and making sure he understands what he needs to do to improve (d) checking he has done his homework fully and packed his bag for tomorrow.
It is important to my mind not to sit over him while he does it, not to issue instructions about what to put in it. My aim is that by year 9 he will be well positioned to be able to manage this all for himself, which honestly some of my undergrads still really need to learn...

I 'casually' ask dd "Have you got much homework tonight" and I help her if she asks me, but that's it. I'm a big believer in letting her be responsible for it herself and take the consequences if she doesn't do it on time. That has very much worked so far (she's 12 and in yr 8). If she were failing to do it then I would step in, but only by making sure it had been done, not by actually sitting with her while she did it. I tend to think that kids who aren't made to take responsibility for their homework in the early days will still need nagging when they are 17.

Every child is of course different and they all mature at different rates. But I'd be really reluctant to undermine a 12 year old's healthy, independent, mature and responsible attitude towards homework! When my dc decided he needed to put a little more effort into maths, I found some online resources he liked (BBC bitesize, I think) and reminded him each day of his desire to do some more practising coming up to exams, but stayed well clear of any further involvement in what he did. I also suggested that 20 minutes daily would be far better than the impossible task he'd set of 8 hours per day on the weekend!

However it is quite obvious that the more a child is helped, the better they will do at school.

But possibly the worse they'll do when they eventually have to take responsibility for themselves!

Everyone on MN is going to say no you don't need to up your involvement.
