Want to make Chaucer relevant to 15-year-old's? Lighten-up a little bit and allow them to laugh. This lesson in the hands of a savvy teacher can open the students' eyes to various concepts of Chaucer's medieval world: including social mores, early criticism of the Church, an increasingly bold humanist voice, and of course a human sense of humor. Introduce Canterbury Tales in this manner and then get out of the way as your students will investigate passages on their own looking for the racy, the raunchy, and the real Chaucer.
This is also available in a Prezi if preferred.
