Here is a Cultural Literacy worksheet on Leaves of Grass ; the book actually went through numerous editions, depending on how one counts them. That count, in any case, includes the famous “deathbed edition,” which had grown to almost 400 poems from the 12 in the first edition.
Walt Whitman is a central figure in American letters and Leaves of Grass a milestone in American poetry. I can’t imagine why high school students shouldn’t learn something about him. Moreover, Whitman can serve as a means of introducing students to the concept of free verse–again, something high school students should understand, and be able to understand.
