Here are some interesting sites on mathematics education:

Through the NCTM, a number of resources are available, such as the electronic version of Principles and Standards of School Mathematics.

The Math Forum is an online “Math Education Community Center” with links to Web resources, teaching materials, online discussion groups with other teachers, problems of the week (for grades 3-12), Ask Dr. Math (for math questions), and Teacher2Teacher (for teaching questions). You can browse and/or search K-12 lesson plans according to topic or grade level.

Math Archives offers online teaching materials and links, with such focal areas as Calculus Resources On-line, Graphing Calculators, JAVA and Other Interactive WWW Pages, Lessons, Tutorials, and Lecture Notes, Sites with K-12 Teaching Materials in Mathematics, and Visual Calculus. At its K-12 Teaching Materials, information can be obtained about Lesson Plans, Software, Topics in Mathematics, Contests and Competitions, and other topics of interest. At its Topics in Mathematics, useful information is accessible in such areas as Arithmetic, Algebra, Geometry, Trigonometry, Pre-calculus, Calculus, Statistics, and other areas.

Math Central is “a service for people involved in mathematics education from kindergarten to grade twelve”. It is “a meeting place for teachers to share resources, a service to teachers, students and parents who may need an answer to a mathematical question and a facility to allow teachers to carry on a dialogue amongst themselves” (through Teacher Talk).

The Eisenhower National Clearinghouse was created to “identify effective curriculum resources, create high-quality professional development materials, and disseminate useful information and products to improve K-12 mathematics and science teaching and learning.”

Coordinated by Scott Mandel, Teachers Helping Teachers is intended to is to provide some basic mathematics teaching tips, new ideas in methodologies, and a forum for sharing expertise with colleagues. Lesson plans and activities for mathematics teachers are also offered.

The Geometry Center at the University of Minnesota offers a repository for materials and projects relationg to the computation and visualization of geometric structures. Links to educational materials are also available.

Created with funding through the NASA Dryden Flight Research Center in Edwards, California, math activities based on NASA projects and aeronautical themes are provided for K-12 teachers.

Though the NSA’s Mathematics Education Partnership Program (MEPP) outreach program promoting mathematics and science education, learning units are available that were created through NSA-sponsored teacher workshops (Summer Institutes for Mathematics and Elementary Teachers).

Launched in December of 1999, Figure This – Math Challenges for Families campaign is intended to involve parents in their children’s education and help parents encourage their 10 to 14-year old children to do math problems together after school. Sample challenges and an index of the mathematics covered in the challenges can be obtained at the site . Also, there is a related Math is Power site.

Part of a research and development effort to deliver a full range of information resources to educators and students by the University of Kansas, the Explorer offers browsable and searchable curricular materials in mathematics.

The Columbia Education Center provides lesson plans created by teachers for use in their own classrooms. Materials are offered for the elementary (K-5), intermediate (6-8), and high school (9-12) levels.

The home page for the University of British Columbia’s Electronic Games for Education in Math and Science or E-Gems, with links to several of their “current research projects”, in which they “focus on the human-computer interaction issues associated with learning in an electronic game environment.” One of their goals is to “engage learners (9-14) in conscious reflective exploration of math concepts” which can be integrated with other forms of education.

George Pólya’s problem solving tips in “How to Solve It”.


Here are some interesting sites on fractal geometry and chaos theory:

As described in the last chapter of their text Fractals, Graphics, and Mathematics Education, Michael Frame and Benoit Mandelbrot have created a Panorama of Fractals and Their Uses. This is intended to be a detailed wordbook or lexicon that orders alphabetically a wide mixture of fractal uses for the classroom. Frame and Mandelbrot also provide information on their introductory course in fractal geometry at Yale University, including some details on possible fractal software.

Kenneth Monks at the University of Scranton provides a couple of versions of his chapter Fractal Themes at Every Level, as well as his fractal course software and some of his pertinent student papers.

Robert Devaney at Boston University offers an interactive version of his chapter on The Fractal Geometry of the Mandelbrot Set: Periods of the Bulbs. Also, see his NSF-sponsored Dynamical Systems and Technology Project for ideas on effectively using technology to integrate fractals and chaos into the classroom.

Cynthia Lanius at Rice University details a fractals unit for elementary and middle school students that “adults are free to enjoy”. The unit describes various fractal properties and involves creating and interpreting such figures as the Sierpinski triangle, Jurassic Park fractal, and Koch snowflake.

Florida Atlantic University and the Broward County School District offer Pattern Exploration: Integrating Math and Science for the Middle School, containing a rich collection of fractal geometry teacher enhancement materials created through a joint NSF grant.

Eric Weisstein’s World of Mathematics (a web resource of Wolfram, the maker of the CAS Mathematica) contains information about fractals and links to pertinent topics and resources. Also, Alexander Walz provides information on fractals and their creation using the CAS Maple V.

Mathematics Archives and the Math Forum both provide a variety of fractal information and links to other online resources.

The Maryland Chaos Group provides a Chaos Gallery with interesting fractal graphics, chaos animations, and links to pertinent mathematics.

Robert Doerner’s Interacting with Chaos deals with non-linear dynamics and chaos and discusses four sample systems, starting with the logistic map and ending with the driven damped pendulum.

Tom Stoppard’s Arcadia may also be of interest.

The journal FRACTALS publishes peer-reviewed work in the form of full-length research papers, short communications, reviews of both technical and pedagogical nature, and popular articles. The table of contents and paper abstracts for previous issues are accessible.

As suggested by a number of the contributors to the text, one particularly effective means to generate fractal graphics is through the freeware fractal generator Fractint, created for IBM PCs and compatible computers.

There are many pages that offer interesting facts about mathematics and mathematicians. For example, the following sites may be of interest:

Harvey Mudd College’s Fun Facts, an archive of interesting mathematical facts.

Steven Finch’s information on various mathematical constants.

Jeff Miller’s information on various mathematical symbols, mathematical words, and mathematicians on stamps.

Mark Woodard’s examples of mathematician quotes.

Here are some interesting sites on the history of mathematics:
