This drill involves giving students some prompt which they are to become increasingly aware of. To do this, supply the prompt at the beginning of class, and track the number of times people commit the prompt on a sheet of paper or the whiteboard. An example might be telling them a physical action like touching of the face. Whenever anyone touches their face, put a tick mark on the tracker. Track the times they do this common thing according to when it happens during the class duration; in other words, for a one hour class one might break the class into 15 minute segments. The reason for this is to show that the actions lessen as the class goes on and people become more aware of it. Finish the lesson by explaining how simple awareness of an action or habit helps curtail its frequency.
