Parent here, and I have to give full kudos to DD's school and teachers.
1st Lockdown was a shambles. This one is so slick it's a miracle.
They're using Teams, and setting assignments. Kids watch the inbuilt videos and teaching sessions, follow links, listen to files and answer directly into the powerpoint or word document - which can also be downloaded and printed if needed. They then 'hand in' the assignment back to the teacher, who can view and comment and mark directly.
They can also message directly, and to each other to ask for help. School have been setting Maths, Reasoning, English, SpaG and Guided Reading everyday. We also get a weekly Music lesson (and it's technical theory - very well done), 2x science and history assignments per week, to be completed over more than one day in stages, plus weekly PHSE, and assembly and some other topic-y bits. No filler, no make work and the whole thing is designed to be independently completable - so no 'make a volcano' needing parental involvement. We also have Bug Club for assigned reading books as well.
It's very well done, and very low effort on my part. I'm having to step in to help and prompt, but I'm not having to do hours of uploading or admin. so far, DD is 100% of assignments and I see no reason it won't stay that way.
