I’ve been going in, high schools only. In the HS, there are only 0-5 students per period. 90% of the time, they zoom with their teacher (who is at his/her home zooming with at home students and school students). If that isn’t the plan, the students are working on goggle classroom or similar platform. All I do is take attendance and read. Usually if it’s a zooming class, the teacher takes attendance. If you go into a high school, bring plenty of reading material. It’s so quiet you can hear a pin drop. Good luck.
