From the text: The 2012 U.S. presidential election is the perfect opportunity to present a timely civics lesson on how a U.S. president is elected. More important, it offers opportunities for students to reason mathematically about election issues  for example, about how much time and resources the candidates should invest in particular states. The results of the previous U.S. presidential election provide an ideal backdrop for introducing the electoral voting system, weighted voting, and the Banzhaf and ShapleyShubik power indices. Investigating these concepts, students will solve authentic, realworld problems and value the utility of mathematics.
