# Vampires: Fact or Fiction?

Students predict how many vampires are in the world, based on the legend that, once bitten, each victim becomes a vampire. Extrapolating how many vampires would populate the earth in 30+ weeks, students then compare the total predicted vampire population against earth's total human population. This creative lesson by Microsoft improves math, problem solving, and group skills. This activity is great since The Twilight Saga is such a big hit right now. Computer access and Microsoft Excel are needed in order to complete this particular activity.
