10Ticks is a montage of free mathematics lessons, worksheets, and games based on the UK's National Numeracy Strategy. One of the most popular attractions of the Web site is Pac Math, a fun game that allows children to practice basic arithmetic. Over 200 worksheets discuss topics in algebra, geometrical shapes and spaces, statistics, and more. Several more features are available after registration....

The Mathematical Association of America (MAA) has developed the Loci site to bring high-quality instructional materials to math educators everywhere. One of their more recent offerings is this article by Michael Grady of Southern Utah University on how to add animations to geometric constructions. The piece talks about how users might use computers and open source ray tracing software to add the...

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 resource, provided by Professor David Joyce of Clark University, is an excellent examples of how Java can be used to explain basic principles of geometry and trigonometry. A Short Course in Trigonometry is divided into thirteen sections, accompanied by instructive Java applets and selected answered exercises. Professor Joyce shows a wonderful ability to simplify complex concepts and demystify...

Utilizing dynamic models to explain different aspects of geometry can be a powerful pedagogical tool. This is exactly what inspired Eduardo Veloso and Rita Bastos to write this classroom exercise for the Mathematical Association of America's "Convergence" site. In this exercise, mathematics educators will receive an introduction to several key aspects of the history of geometry through four...

You've probably been to a playground, but have you been to the Geometry Playground? It's just as much fun, and it may change the way you think about geometry. Created by the good folks at the Exploratorium in San Francisco, this exhibit is meant to complement the traveling exhibit which has been featured in other science museums around the United States. The exhibit here contains three sections:...

The Exploratorium is a multifaceted museum of "science, art, and human perception" on Pier 15 in San Francisco. The museum's website veritably bursts with educational resources, among them this page of activities designed to bring geometry to life for kids kindergarten-age through eighth grade. Here teachers, parents, tutors, and caretakers will find enlivening activities like the Geometry...

Basic geometry resources are always in demand, and educators and students alike will breathe an easy sigh of relief as they are introduced to this set of resources dedicated to this ancient branch of mathematics. Provided by Eric Weisstein at Wolfram Research, the site is simple to navigate and is divided into subtopics that include coordinate geometry, dissection, distance, line geometry, and...

This metasite "collects various areas in which ideas from discrete and computational geometry (meaning mainly low-dimensional Euclidean geometry) meet some real world applications," according to the site's provider, Dr. David Eppstein of the University of California at Irvine. Categories available include Geometric References and Techniques, Design and Manufacturing, Graphics and Visualization,...

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...
