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,...

How do you solve a problem like solids, mathematically speaking? Well, you could use this rather fascinating resource provided by the Convergence magazine. Offered as an educational resource by the Mathematical Association of America (MAA), this particular resource brings together the work of the Franciscan friar Luca Pacioli (c.1445-1509) and the geometric sketches of Leonardo Da Vinci. Both men...

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...

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. After doing so, a set of relevant materials will be offered to them, organized by topic and intended grade...

In the introduction to this site we learn that, "A fundamental result of geometry, used often in secondary and collegiate mathematics, is the equality of ratios of corresponding sides in similar triangles." Accordingly, this concept is expected knowledge of students in physics, engineering, and the sciences, "since its simple statement is rather useful in finding unknown lengths of elementary...

Science UTM offers online articles and activities "for people who like science." Science U and the web-design and development company that owns and operates the website, Geometry Technologies, were formed as a result of the closure of The Geometry Center at the University of Minnesota. One of the conditions of that grant, which funded The Geometry Center and ended in 1998, was that the Center...

Developed by Barbara Kaskosz of the University of Rhode Island and Doug Ensley of Shippensburg University, this resource from The Mathematical Association of America's Digital Classroom Resources collection will prove quite valuable for educators and anyone with an interest in computer graphics or geometry. Through this resource, visitors will learn how to draw and rotate 3D objects via a series...

The University of Minnesota Geometry Center is a mathematics research and education center that supports math and computer science research, mathematical visualization, software development, application development, video animation production, and K-16 math education. The website describes some of their projects that use technology to visualize and communicate mathematics and related sciences....

You may as well admit that although you appreciate the beauty of the small snub icosicosidodecahedron, you aren't as clear as you might be on the theory behind it. This site can help; here you can view over 850 polyhedra (three dimensional objects bounded by polygons) in VRML format (there are several VRML plug-ins available for the major browsers, and instructions are provided on the site)....
