Generally speaking, I like teachers who are humorous and open. Of course, responsible teachers deserve respect. Such a teacher has a good teaching level.

Mathematics is closely related to life, which can make students feel the charm of mathematics from life. When appropriate, they can do some classroom interaction in mathematics, communicate with class representatives and learn about students' learning. Don't criticize students casually. High school students are in adolescence, extremely sensitive, and will be impressed by friendly teachers who have encouraged them.
