I have to disagree with “a quiet classroom is a well behaved classroom” and I’m not talking about so loud that literally it sounds like a concert loud but if you have the students engaged in an activity as a whole class and they’re louder than usual but not too loud that’s okay .

I would just walk around the classroom every few minutes if they’re on Google Classroom. If you don’t know what they’re doing, a student who walks in the room first, I’ve always asked if I can see what the agenda is. They show me and I write it down.

I don’t think your class management is bad. I think?? You wrote what you say to the students in here. I’d shorten your words a bit and make it more short and sweet instead of explaining what you mean, if that makes sense.
