History Channel put together a 22 minute video in a quiz show format that discusses red states vs blue states which is perfect when discussing political parties. When I looked on-line for a viewing guide, I could not find what I was looking for so I created my own. I have students trying to answer some of the questions asked on the show before they watch it. As they watch the episode, they complete the worksheet and then conclude with a brief writing assignment taken from the questions posed on the episode guide on the History Channel's website.
The link to the video is posted with the answer key and is listed here as well: http://www.history.com/shows/how-the-states-got-their-shapes/videos/playlists/full-episodes#how-the-states-got-their-shapes-north-vs-south
