I would also ask - again - whether a live lesson is the best form of education.
I did weekly Zoom meetings / lessons with groups in lockdown. With 10 at a time, t was great and interactive. With a full class, it wasn't - children could be off task, doing other things. I would much rather record an introduction - hello, this is your work for the day, recorded Powerpoint or whatever, then be available for enquiries as they come in and available to give feedback on submitted work, plus maybe a 'sweep up' at the end to clear up misunderstandings.
