Take a walk through time, 1852 to 1994, following the mathematical history and development of the Four-Color Theorem. Learners take on the role of cartographers to study an imaginary world of countries that need to be mapped. One rule: no adjacent country can be the same color. One question: What is the minimum number of colors the map maker should keep in stock?
