It is random with regard to what every school is doing because, unfortunately, the funding isn't there to ensure every school is the same. By way of equipment, premises etc.,
OP the best thing you can do is to contact your school. Ask them a) are the kids being supervised doing the work that is set and b) tell them you are going to send the children in with the work that has been set for them (the stuff the school is sending home) and you want them to ensure the children do it as part of their school day. You cannot be expected to home school having done a shift.
DS is lucky, by the look of this thread. His school has Chromebooks for every child, they're all very well versed in on line work - all homework has always been set on line via remote classrooms. So the kids are used to logging on and getting stuck in.
The Hub for keyworker children is at the local secondary school as it's big. But the teachers from the primaries are taking their own classrooms so there aren't any 'new' teachers. Some will be teachers from other years but they are familiar as they are seen around the respective school. It's just that they are all joined together now.
Just to make you, hopefully, feel better regarding the kids education. This is DS's at home schooling today.
English - carry on with a week long project looking at Shakespeare's Tempest. Different question sheet for each day. He's decided to break it into 5 segments, some friends are doing the lot in one day.
Maths - Mathswatch questions - 10 in total.
Languages - a worksheet that needs to be in by next Monday - five pages long. Again he's doing one a day.
History - read a piece about WWII and do a brief questionnaire.
He finished that lot about 10.30am. I've given him a 30 minute break then told him to go into Oak Academy and Bitesize and look at stuff he knows he's weak on. I've monitored that, on and off, as I had some WFH things to do.
This afternoon he'll watch a film and at 3pm he'll start his 2 hours on the PS4 which he plays, remotely, with his friends. It's his regularly thing and keeps him in touch with his friends as well as keeping his spirits up so it's a given.
And that's it. That's his education. Yes, we do watch history programmes in the evening sometimes, yes we do encourage him to read (newspapers, magazines as well as books obviously), yes we do watch quiz programmes like Only Connect, Richard Osman's House of Games, University Challenge, to keep the brain working fast. We play board games in the evening or do a couple of rounds of Uno - just to have a some fun and, again, keep the brain active. But we also snuggle up to watch Marvel films (last night we watched Daddy's Home). It is a scary and disconcerting time for children - if Thor or Will Farrell can take DS's mind off it all then I'm shoving that in the DVD player and having some fun.
There's nothing DS is getting that your children aren't...UNLESS their school isn't supervising work or is allowing them to play rather than do set work - in which case it's a matter for you and the school to sort out.
