How does the teacher observe the pupils in the classroom?

They usually look around to see what you are doing. For example during a test they may watch as you tap your pencil. They don't generally don't care about the little things you do. Teachers can also tell if you have had or are having a bad day. They see you enough to know what a good day looks like compared to a bad one. Just don't ever let them observe you coping another student's test. That is not ok to cheat on ANYthing!
