1. Next time you're at the library, check out the "I Hate Mathematics Book", by Marilyn Burns. No matter what you thought when you started, you'll want to rename the book before you're through!

2. Play games on a torus! Start on the main page to figure out what a torus is and how how the surface works. Then try the maze. When you manage that, challenge yourself with torus tic tac toe. Ready to try playing games on even more mind-boggling surfaces? Go back to the main page and try the games on a Klein Bottle!

4. Count the cubes. Sound easy? You’re being timed, and the pictures are 3-d. Better use some math and have a good sense of perspective.

5. Try some fun estimating games. Try several of the different options, ranging from estimating the number of objects to estimating other things like length, area, and the size of angles.

6. Next time you're at the library, look for The Number Devil, by Hans Magnus Enzensberger. In accessible terms and in the context of a fictional story, it explains a wide range of math topics including prime numbers, triangular numbers, Fibbonaci numbers, Pascal's triangle, permutations, and more.

7. Try this excellent collection of archived “problems of the week,” adaptable for different difficulty levels.

8. Find a path through the maze following the number rules.
