Investigating Gerrymandering and the Math Behind Partisan Maps

Gerrymandering is very interesting indeed, and a great tool for large states since computer mapping tools have made it evermore powerful. This can be concerning when it comes to election, but it’ll be ok. It is crazy how some of the graphs look weird like creatures/things, but it’s a fun way to start a new topic. But not every map come out right or exact, this due to an efficiency gap, were some of that data wasn’t accounted for or wasted. Gerrymandering has been a very interesting topic, and very informative on how it works with election and how votes can be wasted to make a party seem very victorious or the other.

I find the mathematics of gerrymandering very interesting, but I also find it concerning. It scares me how easy it is to influence the results of elections solely based on grouping. I appreciate the clear explanation. While I am not a teacher and don't plan on it, it was still extremely helpful to help me understand as a student.

I love this lesson plan and want to use it in my math class next year when we do election theory. Is there a way to guarantee that this link won't go dead? . . I could keep a paper copy in my files, but would sure prefer not to.

You can ignore my previous question--still want this permanently, but realized (troglodyte me) that I could make a PDF of it. Thank you for the great help!!

The North Carolina 12th Congressional District shown/identified here was supplanted in early 2016. See https://www.ncleg.net/representation/Content/Plans/PlanPage_DB_2016.asp?... Otherwise, some good lesson material here.

Hi Blake, Thank you for your comment. I updated information regarding North Carolina's 1st and 12th congressional districts, noting that they changed shape on Jan. 3, 2017 as a result of court-ordered redistricting.
