Miss Caroline is introducing herself to the class. She is from North Alabama, specifically Winston County. This is strange to the class because North Alabama tried to secede .
Did you forget your lunch this morning?
Miss Carolina gets upset with Scout on the very first day of school because her father, Atticus Finch, taught her how to read. Miss Carolina told Scout that she's not allowed to be taught by her father anymore.
Are we poor, Atticus?
Scout decides to tell Jem about the situation that happened with Miss Caroline. Jem tells Scout that it's going to be okay and that Miss Caroline is trying a new way of teaching that hasn't been done before.
Miss Caroline was walking around the classroom checking for lunches. She appeared at Walter Cunningham's desk. Walter obviously doesn't have a lunch so he just glanced at her for a while.
Jem, Scout, and Atticus were all having a conversation after school and they were talking about the Cunningham's. The Cunningham's are a really poor family and that idea got Jem thinking that they themselves were poor.
