This document provides instructions for an activity called "That's Sick! Practitioner's Notes" where students pretend to be hypochondriacs at an annual ball, circulating around the room telling each other about their imagined illnesses and symptoms in an effort to outdo each other in appearing the sickest. The teacher is instructed to pre-teach vocabulary related to illnesses, brainstorm examples of illnesses and symptoms, and have students practice complaining about how they feel using sample phrases before sending them around the room to talk to different partners about their ailments for a few minutes at a time.
