To some the word Illuminations may bring to mind Walter Benjamin’s classic work, and still others may imagine those manuscripts that were a product of the medieval intellect and imagination. In this case, the illuminations in question are a set of mathematical teaching and learning tools designed by the National Council of Teachers of Mathematics. Their website was redesigned in early 2006, and is...

In 1999, the State University of New York (SUNY) at Stony Brook's Mathematics Department was ranked fifth in the country by US News and World Report. The department's Institute for Mathematical Sciences (IMS) Preprint Server is searchable and offers full-text preprints (.ps and TeX) from 1990 to the present. Areas of research at Stony Brook include differential geometry, topology, dynamics,...

Designed for educators, the Interactivate website provides numerous high quality resources that assist with the “creation, collection, evaluation, and dissemination of interactive courseware for exploration in science and mathematics.” The What's New area provides interested parties with new and updated activities that are quite compelling. One of the more recent additions is Function Revolution,...

With funding from the National Science Foundation, the Learning & Performance Support Laboratory at the University of Georgia has created this website for mathematics educators. Their primary focus is to build teachers’ mathematical content knowledge through mathematical investigations, and the resources presented here reflect this commitment. The primary mathematical fields covered here include...

The Khan Academy is a "not-for-profit with the goal of changing education for the better by providing a free world-class education to anyone anywhere. " Designed as a type of educational tool and a living archive, the site contains over 2100 videos that include algebra lessons, calculus sessions, cosmology, and developmental math. The "tool" function comes in when visitors discover that they can...

This online toolkit consists of a series of modules "designed to help a linear algebra student learn and practice a basic linear algebra procedure, such as Gauss-Jordan reduction, calculating the determinant, or checking for linear independence." Each module is completely interactive and allows the user to input custom values and parameters. The modules are divided into four separate categories,...

The goal of Math Bits is to offer "fun, yet challenging, lessons and activities." The site was created by two mathematics educators intent on increasing the love of math. The resources provided here are divided into more than two dozen categories, including algebra and geometry. Visitors should also note the Math and the Movies area, as it contains some great ideas on ways to teach math using...

Developed by Peter C. Esser and John W. Pluemer of the Math and Science Center at Southwest Wisconsin Technical College, this site brings together a veritable cornucopia of resources related to learning about applied math, occupational math, elementary algebra, technical science, and the fundamentals of chemistry. First-time visitors will want to start by looking at the "Resources" section. Here...

More and more instructional materials in the field of mathematics can be found online today, though for several years, it was difficult to find high-quality textbooks in their entirety. Fortunately Professor George Cain of the Georgia Institute of Technology has created this website to remedy that situation. As Professor Cain notes on his site, "The writing of textbooks and making them freely...

PBS has developed a number of websites for educators, and their PBS Teachers site has received a number of accolades and high praise from diverse quarters. First-time visitors to the site may wish to first use the drop-down menus here to select a grade range and a topic that interests them.
