This unit for my 9th grade Pre-AP English students includes a PowerPoint presentation on tone and irony, a homework assignment based on the short story "Hills Like White Elephants," and then a 2-day classwork unit on Ernest Hemingway's "Hills Like White Elepheants," which puts their knowledge of tone and irony into practice.
This lesson would really be appropriate for any level of high school English; my only recommendation is that you keep in mind the maturity level, as "Hills Like White Elephants" does contain mature subject matter. However, with Pre-AP 9th grade students, they were able to handle the level of difficulty and maturity early in the year.
This unit does an excellent job of introducing students to tone and irony-- two ideas that are neccessary to understand in order to better analyze short stories such as Hemingway's "Hills Like White Elephants."
