Here is a Cultural Literacy worksheet on the concept of a straw man in argumentation. This is a half-page worksheet with a two-sentence reading (the second of them a long compound) and two comprehension questions. This is a cogent introduction to the topic of the straw man. However, it presupposes an prior understanding of argumentation (and its rules) that some students may not possess. But in our current discursive culture, understanding the straw man, a favorite tool of demagogues, strikes me as vital for the development of critical awareness in students.
