Do your primary age children have live lessons? Mine (age 11 and 9) do not and I'm getting a bit frustrated and concerned for them about their lack of contact with school and other kids in their class.
I kind of understand the school's reasons (safeguarding and not discriminating against families that have more than 1 child but only one device) but even a single daily live lesson would make a difference I think.
In my group of friends (6), all of our children attend different primary schools and most are having some online teaching. Ours get daily short videos from the teacher and some exercises (English and Maths) to do and send back.
