I tend to live stream the first part of my lesson in Teams and then move to the chat in their channel so students can share work. Firefly is where I keep my lesson resources for each week and then I set tasks there when I want to give feedback. KS3 all have blogs that they use as on-line sketchbooks as well.

I have all my classes set up as attendees so no funny business, and the share my screen function is amazing. I also use planet eStream to compress videos, normally just time lapses or videos of me or a student drawing.
