I agree OP. I have a Y10 and a Y8. I'm especially worried about the Y10.
Our school have been as great as they can be. Setting a lot of work online and on their own home/school site plus lots of extra links to Iplayer, OU and YouTube for documentaries etc. Form tutors are phoning us every week.
It is however a bit over-whelming.
As teens (and working from home myself in a garden office so not even in the house!) I have to trust that they're doing things. I've seen they are, but it no way replaces school.
People I see are tending to fall into 2 camps -
Competitive home schooling i.e Waking up at 7am and doing a full timetable, plus extra self directed learning online in extra hours, plus extra curricular baking, exercising, music and craft etc.
Or
Competitive give-no-fucks schooling - dcs not waking up until lunchtime, spending all day on x-box, tv, Netflix etc. Parents declaring on SM that they are WFH and can't school as well and they are going to spend any free time 'enjoying their family'
I'm somewhere in-between I think. But yes, I'm anxious.
