Take a walk through time, 1852 to 2005, following the mathematical history, development, and solution of the Four-Color Theorem. Learners take on the role of cartographers to study a United States map that is to be colored. One rule: no adjacent state can be the same color. One question: What is the minimum number of colors the map maker should keep in stock? Planar graphs and real-life examples are explored and connected to coloring graphs and Euler’s Formula. Chromatic polynomials of graphs, the chromatic number, and chromatic symmetric graphs are presented as well.
