The math department of Harvey Mudd College has a website full of fun math facts. Mudd Math Fun Facts has an easy to search database of math facts designed to stimulate thought and make students look at mathematics in a different light. Each fun fact is accompanied by a problem, diagram, and short explanation of a fun mathematics concept.
Applications for Education
Mudd Math Fun Facts is designed for use with introductory college math courses, but it could also be a great website for some high school mathematics classes. The math fun facts can be used to expose college-bound students to some higher order mathematics concepts and spark some curiosity about mathematics. If you have a class website or blog you can link to Mudd Math Fun Facts and provide students with a fun fact of the day that they can explore on their own.
