I have used this in my classroom when teaching Propaganda and Persuasion. The students are in pairs. Each student receives a different piece of candy (at least different from the partner). Each student has to make a claim as to why his or her candy is better than his or her partner's candy. They fill out the sheet first, then the students will get a chance to persuade the class. The student in the pair who convinces the class his or candy is better, gets the piece of candy. Each student has to write a paragraph at the end.
