this doesn't sound right at all.
I feel a bit crap typing this TBH because it seems like you've been let down and your school was unprepared.
my Y6 (indy) DC are doing remote online learning. The DC were trained how to use it a couple of weeks ago and brought a remote timetable and stack of textbooks home last week. daily registration/form group then an hour of eg. maths, English and science with assignments to upload for marking, then 2 other subjects after lunch with assignments to upload also. Teachers then mark and send feedback. There's also a prep timetable for eg reading, X tables and lots of encouragement for daily sport and DC to upload photos so this week we've had garden cricket and lots of running. Extra curricular music lessons via online also.
The DC can use the remote school for video calls and chat together one to one, and in form & subject groups.
There's a skills challenge (lots of juggling, baking, learning to load a dishwasher
etc) and daily blog video from the head, a variety of daily special awards and info on what other children have been up to via twitter.
I cannot speak highly enough of the school, their handling of this situation and the staff who always work so hard.
Its required minimal involvement from me, DC happy getting on with it so far apart from the odd question about saving/uploading files. They're using my laptop, so I have to work evenings/nights.
