In college I worked at at a donut shop, and I’ll forever remember my boss telling me, “You can always be doing two things at once.” You will learn to master this art quickly. You not only have to teach the lesson, you have to be monitoring all the children as they sit and listen. When working at a table, you are also recording observations (either mentally or on paper), helping the children near you, and also monitoring the rest of the room with your eyes and ears. It’s exhausting. I recommend an aide who can help!
