Study questions in Scholastic's "Frindle" discussion guide address what Mrs. Granger uses as her "battle cry," why some students wanted Mrs. Granger to punish them and why Bud Lawrence wanted to copyright the word "frindle." Scholastic includes suggested answers to each question.
Mrs. Granger's battle cry is "look it up," because she loves the dictionary. One reason students wanted Mrs. Granger to punish them is because of the conflict between her and Nick. By getting punished, other students could join Nick's side and rebel against authority. Bud Lawrence wanted to copyright the word "frindle" so he could profit from it. By copyrighting the word, he can sell pens called "frindles" and capitalize on the word's popularity.
