If you get one question about something you’ve explained, it’s for clarification or context. If you get two or more, you’ve explained it badly.
Not always true, of course – but true often enough to be a helpful reminder. When someone asks a question, it’s for a reason. (And never forget one of the primary rules of teaching: for each person who asks a question, ten more had the question but didn’t ask it out loud.)
When someone asks a clarifying question, that’s your cue to pivot into examples and practice. Make sure everyone actually gets it. Don’t just answer the question and move on.
A question is a gift and an olive branch. Don’t ignore it.
