My niece and nephew go to public school in NYC. They closed at the same time that we did and were up and running with distance learning one week later. MS kid apparently has Zoom classes from 9am to 1pm every day, HS kid has assignments and some taped lectures. I don't know if that's just the way their schools are doing things or if there is some consistency in the curriculum. NYC distributed 300k laptops so that every child has one, also free internet access.
