My wife teaches, my opinion to her was to do online only until the end of the year, then reassess after the holidays. Schools are germ pits boy. Or option 2 would be to just let high schools go back this year, then start the middle and elementary schools up next year depending. My thinking is that high schoolers at least can understand how to wash their hands and socially distance somewhat. Plus your education and sports gets serious in the 9th grade. High schoolers don’t need anymore time away from school imo.
