This website "contains the techniques, tips, and secrets used by master teachers" of mathematics. Based on research, the authors argue that rote memory is one of the least effective ways of memorizing. They offer more effective strategies for teaching students the times tables and some strategies for helping with memorization, such as using rhyming words, pictures, stories and other activities....

Parents often scoff at the powerful calculators their children use for math classes, noting that they had to learn with slide rules. A device that predates both tools, however, is the focus of this unique site. The abacus has roots in the fifth century B.C., and still sees limited use in various parts of the world. A very thorough overview is provided online, with interactive applets that teach...

Great Internet Mersenne Prime Search (GIMPS) promotes a contest for anyone who can find the largest prime number. On November 17, 2003 Michael Shafer's computer, in conjunction with an international grid of 211,000 networked computers found the 40th known Mersenne prime, 220,996,011-1! In addition to articles about this new finding, the website provides a link that allows you to view all 6,320,430...

The material presented on this Web site is primarily suitable for high school and early college mathematics courses. It is divided into four massive sections that are devoted to basic arithmetic, trigonometry, precalculus, and an in-depth look at real numbers. Each section covers almost as many topics as a full course in the subject. The author clearly describes each concept and combines figures...

For people of a certain age, the phrase "math worksheet" may conjure images of pieces of paper with wet purple ink, freshly mimeographed. For others, they might just say: "What's a mimeograph?" Both groups will find things to like about this website, which brings together a number of math worksheets for general use. The site is maintained by Scott Bryce, and while some of the materials require a...

The Mathematical Association of America has developed the Innovative Teaching Exchange in order to facilitate the exchange of interesting and compelling teaching resources from a wide range of educators. As their site indicates, "The intention is to encourage more experimentation with more methods than the traditional lecture/questions method." Currently, there are about a dozen articles available...
