 Election 08 http://election08.cs.uiuc.edu/home.html View estimates for the probability that the two presidential candidates win the election, the expected number of Electoral College votes for Senator Barack Obama (D-IL) and Senator John McCain (R-AZ), and the probability that each candidate will win 300 or more Electoral College votes. Features include: Pick your swing scenario     Strong Democrat     Mild Democrat     Neutral     Mild Republican     Strong Republican Sliders Methodology Archive FAQ The site was developed by computer science and political science students at the University of Illinois. Project Lead the Way http://www.pltw.org/ Project Lead The Way (PLTW) promotes pre-engineering courses for middle and high school students by partnering public schools, higher education institutions and the private sector. Goals of this national, not-for-profit educational program include: increasing the number of young people who pursue engineering and engineering technology programs in four- and two-year post-secondary programs   providing equitable and inclusive opportunities for all academically qualified students   reducing the future college attrition rate in four- and two-year engineering and engineering technology programs   providing leadership and support that will produce continuous improvement and innovation in Science, Technology, Engineering, and Mathematics (STEM) programs Illuminations: Getting into the Electoral College http://illuminations.nctm.org/LessonDetail.aspx?ID=U189 This Illuminations unit explores the mathematics of the Electoral College, the system used in this country to determine the winner in a presidential election. The lessons include activities in percentages, ratios, and area, with a focus throughout on building problem-solving and reasoning skills. They are designed to be used individually to fit within your curriculum at the time of the election. However, time permitting, they can give students a strong understanding of how small variations can make a big difference in who wins a president election.
