I know this probably isn't even being considered, but outdoor classes would be a good solution. This would especially make sense for rural districts that have more space. You'd need to set up those big carnival tents and figure out bathrooms and stuff, and of course you'd have to deal with the kids and families complaining about the bugs/heat/cold/whatever, but IMO it's a much better solution than Zoom classes. As a teacher I'd be excited to do it, all I'd need is some kind of portable white board. In this region we could probably run it almost to Thanksgiving without major problems.
