## Puzzle Sources

Our puzzles section has a collection of math fair puzzles. In addition, there are several websites that have good math-based puzzles, some of which are directly useable in a math fair.

Thinkfun's puzzle site, Puzzles in Education, has many wonderful puzzles that can be downloaded and are ready to use in a classroom.

Math is Fun is a site with many good math fair type puzzles.

That's a good problem. This is Galileo.org's math fair page. The puzzles here are organized by level. No solutions are provided.

NRICH. This is one of Cambridge university's math enrichment sites, aimed at students for ages 5 to 19. The problems are arranged by levels or stage. Although they are good problems, many are more suitable for classroom activities than for presentation at a math fair.

AIMS Puzzle Corner. A collection of over 100 math puzzles presented by the AIMS Education Foundation. Solutions are provided online.

The following books have been recommended by teachers who have used them as resources for math fair puzzles:

, Ivan Moscovich, Workman Publishing, New York, 2001.*1000 Playthinks*, Raymond Blum, Glen Vecchione, Kurt Smith, Steve Ryan, Adam Hart-Davis, Sterling Publishing, 1999.**The Giant Book of Math Fun**

Below are more sources of problems and puzzles. Martin Gardner, one of our patrons, has written many excellent books on mathematical recreations (which was the name of his column that he conducted for years in Scientific American). We list some of his books below but recommend that you investigate many others. Most public libraries stock a good selection of his books.

Another excellent source of puzzles are the books by Dennis Shasha featuring Dr. Ecco. The majority of his puzzles are original, and are wonderful for high-school students. A recent book of his, listed below, includes puzzles that are accessible to students in the elementary and junior high or middle school grades.

We should also mention that quite a few of the problems in the collections by Brian Bolt are almost "math fair ready". From the point of view of sources of problems for math fairs, the ones listed here are probably his best.
