@adaline Unfortunately a lot of parents are currently expected to teach their kids, though.
In Primary I'd expect parents to support their kids learning yes, in so far as practising times tables, reading to them and listening to kids read, and doing an all round kind of education (baking together to measure ingredients kid of stuff). And I expect that even in pre coronavirus times.
I wouldn't expect parents to teach short division, multiplying double digits, factors and multiples, and various grammar terms unless the parents can teach it confidently or there's a risk you'll just all end up frustrated and confused. I've set my pupils a small amount of work I know they can have a go at, that is within their ability, with my contact details attached asking them to contact me if any issues. Otherwise, times tables and reading please!
With secondary (both my kids are teens in GCSE years) I would not expect to teach my child course content, but I would expect to talk to them, support them, provide a quiet space for them, check they have a good work timetable setup, and encourage them to have a go, maybe even look up some tutorials on YouTube or BBC Bitesize. And if all else fails, contact the teacher involved.
