OP, that doesn't sound great tbh. Has the class teacher been in email contact to find out how you're getting on?
DD2 is in Y3 and at a state primary (also have DD1 in yr 6). First of all, we had workbooks to do and good email contact with the class teachers.
Just before Easter hols, the whole school started using Google Classroom with Zoom calls with the class teachers.
DD2 had a Bingo game on Zoom, as part of her French lesson (which was a great idea!). She's also had a couple of class quizzes on Zoom which she really enjoyed!
Lots of work to be done on Google Classroom for both DDs.
DD2 has English, maths, RE, Science, Guided Reading, French, Art, D&T, Topic (different each half-term) and we submit the work and her teacher will mark it and add comments. DD1 has the same too.
We have a workbook from school for maths for DD2. I mark her maths work, and upload it on G/Classroom, so her teacher can see how she's done.
We don't get it all 100% done. I'm a key worker and working more hours that I usually do (as some fellow workers are vulnerable and self-isolating). DH is self-employed, so has (finally!) finished the jobs around the house that he hadn't had time to do whilst working! We both help DDs with school work.
We do what we can and I upload the work on G/Classroom and I try to comment as much as I can, on what DDs enjoyed, or struggled with, etc.
DD1 has SEN so it's takes her a little longer to get her work done. But, her teacher has been understanding and is aware that we can't get 100% of her work done. Our school SENCo has also been in contact by phone a few times to see how's she coping with her work, etc.
Sorry you've not had as much support from your DD's school. It's not very helpful if the current way to view and submit work is so non user-friendly!
Can you speak to the Headteacher and ask for more communication between school/parents? So you don't feel so isolated and 'cast adrift'? x
