In Chapter 5, how does Grant treat his pupils?

In a foul mood, Grant punishes his students for the slightest offenses, though they try to avoid upsetting him. After a few hours, he steps outside and surveys the homes near his school. He knows many details about the troubled lives of their inhabitants. When he returns to his classroom, he finds a student playing with an insect. He sneaks up behind the young boy and slaps him hard across the back of the head with his ruler. Furious, Grant finds himself telling the class about the task Miss Emma has set for him. He explains how Jefferson will die and says he must make Jefferson into a man, which is exactly what he is trying to do with them.
