Thinking outside the box here (I'm sure there's 100 reasons why it won't work, but...): 1) Have high school kids learn virtually, use the high schools as additional space for junior high and grade school kids to "spread out" so they are in contact with fewer kids at their school. 2) Switch the virtual days to Saturday and Sunday when the parents are (typically) home from work. Few people go on vacation during the school year, so why not have the off days be Monday/Tuesday? Have Sunday morning off for religious services, school Sunday afternoon. From what I gather, not really, as many companies have brought back "essential" employees (Directors and above) to the office, typically at 25% or less of building capacity. But there is a ton of empty hotel conference room space. Not an option for rural kids, but for city/suburban kids could be a way to spread out and be in contact with fewer kids at their school. Get a big conference room, desks every six feet, project the lessons on a screen and have teachers in booths behind plexiglass for individual 1:1 sessions throughout the day.
