Show your students this really cute segment comparing how the Electoral College functions in our elections to what students think is fair and just. From the New York Times, Electoral College 101.
After showing the video consider asking your students what the grouping of students must have been for "colored pencils" to win the class electoral college? Is there more than one possibility? What is the minimum number of students that could have voted for colored pencils for them to still win the Electoral College. Students then consider scenarios where a candidate wins the popular vote, but loses the Electoral College.
