Center for Voting and Democracy
http://www.igc.org/cvd/
Excellent site! "The Center for Voting and Democracy researches and disseminates information on how voting systems affect voter participation, accountable governance and fair representation. We specialize in reapportionment and the broad range of proportional representation systems that allow most voters to elect representatives of their choice."

Census 2000 and the Congressional Apportionment
http://www.census.gov/dmd/www/apportionment.html
Gives the history of congressional apportionment and explains the method that is currently used to calculate apportionment.

Math Forum: Discrete Math
http://forum.swarthmore.edu/discrete/discrete.html
Classroom materials, software, Internet projects, and discussion forums.

Discrete Mathematics Project: Discrete Mathematics Activities
http://www.colorado.edu/education/DMP/activities/index.html
Includes several activities for each of the following topics: Election Theory, Fair Division, Graph Theory, Counting Techniques, Discrete Probability, Matrix Models, Mathematics of Iteration/Recursion.

Fair Division
http://www.math.hmc.edu/~su/fairdivision/
Page from a math professor at Harvey Mudd College which includes a link to a Fair Division calculator (Java applet).

Math 131
http://saturn.vcu.edu/~gasmerom/MAT131.html
Page from a math professor at Virginia Commonwealth University which includes links to lecture notes treating fair division.

Villanova U MAT1220
http://renoir.vill.edu/math/archives/mat1220/examples/00readme.html
Yet another page from a math professor, describing the course "Discrete Mathematics with Social Science Applications" - probably more useful for you as an instructor than to the students directly; some links to software.
