This article describes the authors' use of three game shows--"Survivor," "The Biggest Loser," and "Deal or No Deal?"--to determine to what degree students engaged in mathematical thinking: specializing, conjecturing, generalizing, and convincing (Burton, 1984). Student responses to the task of creating winning strategies to these shows were collected and analyzed. The data showed that students generally did not engage in the process of mathematical thinking unless directed to do so and the effects this had on the students' responses is discussed.
