Freaky Freshmen
In Chapter 10: Trouble Makers, she is first seen helping Jeffrey understand a new math assignment she just gave him. She then tries to teach her class about Fractions, but she fails to do so when Willie ends up causing trouble and distractions for everyone else. She grabs Willie's arm and tries to pull it away from the projector when she catches him messing with it, but he moves his hand into the light accusing her of doing it and "burning his hand". Everyone who witnessed the situation is called to the office to tell the Principal what they believed happened and they all have different stories.

In Chapter 11: Getting My Way, she doesn't appear, but is actually mentioned by Miss Calkins that she was fired after the mishap with Willie the previous day.
