The good folks at the Mathematical Association of America (MAA) are always on the lookout for mathematical principles in the least likely of places, and this gallery of "found math" is a tribute to their perspicacity. The exhibition includes prizewinners from the Joint Mathematics Meetings Exhibition of Mathematical Art and a weekly "found math" object. Visitors can make their way through items...

A number of online textbooks have been created in the past several years, and this course in linear algebra is a nice addition to the existing repertoire of such educational materials. Professor Rob Beezer of the University of Puget Sound created this introductory textbook, and he still maintains the site and provides updates periodically. The material covered in the textbook includes systems of...

Under the motto, "Show me how, now!" Algebasics is a fine online mathematics instructional resource that takes young and old alike through the basics of algebra. The breadth of the material is divided into sixteen sections, which begin with, well, "the basics", and proceed all the way to a section on applying algebra to real-world situations. Each section asks users to solve a number of problems...

The self-proclaimed "autodidact math enthusiasts" behind Algebrarules.com write that they were "looking for all the rules of basic algebra presented consistently in one place" but couldn't find one. So they created Algebrarules.com, a sleek and easily browsable online resource for rules of arithmetic, exponents, and radicals. Visitors can browse for rules in these categories by selecting tabs that...

The American Mathematical Society (AMS) was founded in 1888 in order to further mathematical research and scholarship. Since that time, they have embarked on a number of outreach programs designed to educate the public about the importance of various mathematical endeavors. In the past several years, they have been developing the AMS Books Online website, and it's quite a resource. The works were...

Developed by Dr. Abdelkader Dendane, a lecturer at the United Arab Emirates University, the Analyze Math website is designed to provide curious minds with access to in-depth tutorials on such topics as logarithmic functions, systems of linear equations, and calculus. The site also covers materials from the fields of trigonometry and the sometimes vexing field of statistics. Utilizing Java applets,...

This wide-ranging and informative online course from Annenberg Learner can be a powerful resource for both high school and K-8 teachers. The site features 10 two-and-a-half hour sessions on a range of related topics, starting with an overview of Algebraic Thinking, moving through Patterns in Context, Functions and Algorithms, Proportional Reasoning, and other topics before finally culminating in a...

Bates College in Maine has worked diligently to bring together this set of mathematical resources to the public, and it's a nice find. The materials here are drawn from four courses at the school: Math 105, Math 106, Math 205, and Math 206. The first couple of resources in each section contain past quizzes and exams from each course, complete with information on each topic. Additionally, each area...

Based at the University of Plymouth, the Centre for Innovation in Mathematics Teaching has developed many instructional materials designed to help both novice and experienced math teachers. This particular area of their website provides access to a number of interactive mathematics tutorials. The materials are divided into eight units, including those that deal with factors, mathematical diagrams,...

The introduction to this site remarks, "If you need help in college algebra, you have come to the right place." Their statement is accurate, as the staff members at the West Texas A&M University's Virtual Math Lab have done a fine job creating a series of online algebra tutorials for students and anyone else who might be returning to the world of algebra. First-time visitors should look at their...
