I saw a lesson on the same topic with another class recently and I planned to lead the lesson in the same spirit. But there were circumstances for which I was not prepared and I did not know how to deal with them. The lesson began, the students settled down. There was a pupil (Pavel) sitting in the front desk, who has a disorder and always has an assistant in class.
