I live in a place outside the UK where schools went online when lockdown happened.
Every child was given a Chromebook and headphones. This was regardless of whether the families had their own iPads or whatever, and it was done so that if any tech issues arose, everyone had help available from the tech desk. Zoom classes got up and running after a hiatus of three days when the lockdown was first announced. The first few week were a steep learning curve.
Families without solid internet access got internet paid for by the school district.
School halls were opened for students of all grades whose parents were working, staffed by some teachers and TAs and people able to deal with tech issues. The kids sat at their desks all day with windows open, jackets on, headphones in place, masks on. They ate packed lunches at their desks and got out for a run around at whatever time their individual zoom class had recess, with masks on.
Kids receiving free school lunch were able to pick up imperishable packages on Mondays and Fridays from the schools. This programme was extended to all families who wanted a package as time went on, as it was recognised that family circumstances were changing. No questions asked.
The problem in the UK wasn't the lockdown. It was the lack of ability to understand that a lockdown isn't just a matter of shutting everything down. It required putting lots of educational and nutritional supports in place and spending billions more than the government wanted to spend.
