In this exercise, I ask my Craft of Prose students to think about the ways in which one element of their worlds—sports—can reveal a great deal about cultural values in addition to demonstrating some of what’s possible. With the class having just read about the Quidditch World Cup in Harry Potter and the Goblet of Fire and been introduced briefly to other examples of games popular fiction, they will create their own sport, have a partner demonstrate, in a charades-like fashion, how that sport works, so that the writer m then ask themselves if they effectively described the sport in “All in Good Sport.”
