My Ten Favorite (Undergraduate Accessible) Sites for Recreational Mathematics

10. An excellent site to learn more about primes for students of various backgrounds.

9. The Fibonacci Numbers are easy to define but never seem to run out new properties waiting to be discovered.  This is a nice site devoted to them.

8. The number Pi also seems a common source of both interest and wonder. My favorite Pi site went down recently, so for now I'll leave a temporary link to this song.

7. This page has a nice library, indexed by subject.  Plus Steven Wolfram is just really cool.

6. This small site contains nice answers to many questions undergraduates seem to be interested in.

5. This site is great for the non-Mathematician designed to correct common misconceptions. They also have some intelligent reviews.

4. This site is a collection of many of the more graphical Mathematics links.  Be sure to check out the Mathematician trading cards if you visit.
