Here's a great way to supplement your math textbook and keep your students interested--
Mudd Math Fun Facts. Hosted by the Harvey Mudd College Math Department, this site currently has 203 fun facts covering algebra, calculus, geometry, probability and more. You can search for a random fact by subject area or by level of difficulty. To those math teachers who thought there wasn't anything on the web for their classes, this is a nice place to start.
