Abstract

In light of the upcoming Winter Olympic Games, a mathematical modeling problem involving algebra and geometry is presented via dynamic geometry software in the context of pairsfigure skating. The death spiral involves a lady's and man's forming concentric circles with their blades on the ice. In-service elementary, middle and high school teachers used knowledge of rates and circumference to solve problems involving the death spiral. Teachers' work is analyzed and discussed.
