Grab some colored pencils and doodle along as we explore the answer to this 150 year old mathematics and cartography question, “Can any map really be colored with just four colors?”

Class experience

This topology course is part of a series of advanced mathematics topics presented in a hands-on format that is accessible to middle school students. 

Students will be introduced to the use of counter-examples in mathematical proofs.

Students will be given the opportunity to explain the premise of the four color theorem, namely that “given any separation of a plane into contiguous regions, the regions can be colored using at most four colors so that no two adjacent regions have the same color.”

Students will explore the concept of reduction. That is, replacing a complex problem with a simplified version to find potential patterns that can be applied to the more complex situation.
