I note the class attendance on the left side of the whiteboard and write a check next to a name when I’ve asked that student a question. This is not dependent on whether they answered correctly. It’s just a tool to help me make sure I interact with each student at least once per lesson.

If the class is getting to rowdy, I simply raise my hand and say “High five please!” and wait for each of them to raise their hand, stop what they’re doing, and look at me. Typically they will remind each other if someone is not paying attention, but I absolutely don’t move on until everyone does it.
