We’ve chosen not to get too involved as I think at this age it’s important to learn to deal with this yourself. Structure time, have a homework timetable, do a weekly plan etc are all things that has to be learnt during these years, or they’ll struggle once they’re older and don’t have the tools.
If they fail now. The worst they can get is detention, but it doesn’t really matter. Later on, if they don’t know how to study - a lot more is at stake.
DS1 makes a plan every Sunday of which subjects to focus on each day, then every day after school he double checks it against the homework given that day. He’s done the same for years. Sometimes he’s tired and he opts for chill time instead, and then he either doesn’t do that homework or he catches up later. Either way, it’s up to him.
DS2 is younger but copying his brother and we’ve backed off there too.
It seems to work. They both get top grades, and of course we help if they ask. But it’s always up to them to ask.
The school doesn’t like the parents helping too much, hence all homework is only communicated to the children.
