Quizzes for The Catcher in the Rye ch. 2-24. These quizzes are challenging, so if your students are reading Sparknotes only, they will not be able to pass these! I have given these quizzes after each reading assignment (some are for two or three chapters) for years, and now 99% of my students read the actual book and not just summaries online. These quizzes are challenging!
Also, just a tip...I do not grade every quiz. Rather, I collect all of them and only grade a select few; the students do not know which ones I will grade, so they must do well on all of them if they want to improve their chances for a high quiz average.
