ab: 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 Shapley-Shubik power indices. Investigating
these concepts, students will solve authentic, real-world problems and
value the utility of mathematics.
