Nick, the main character of Frindle, has managed for most of his school career to control his classrooms and teachers with various distracting behaviors. However, in fifth grade he meets his teacher Mrs. Granger who is a match for his wit and misbehavior. She is known to have a sense of humor but is equally well known for her strict class management and fondness for anything to do with language.
Right away Nick tests her with chaos over his insistence of using the word frindle for a pen. The frindle insanity continues but at each turn, Mrs. Granger manages to maintain or regain class control. Nick has a habit of asking questions, for example, that have no real connection or answer, just to maintain class control. However, when Mrs. Granger takes the questions seriously she turns what Nick wanted, a distraction, into a real learning conversation.
Without the means to control the classroom because of his new fifth grade teacher, Nick feels it will be a very long year.
