Department of Mathematics Education
Here are some links to a few mathematics resources
on the Internet that I have found useful or interesting. I long
ago gave up any effort to construct a comprehensive list.
This site was recommened by Samantha, a student in Ms. Smith's 4th grade class at Brighter Futures Charter School in California.
Lots of formulas, identities, tables, series, etc.
Information on selected mathematics topics such as mapping, graph theory, knot theory, algorithms, computer science, and infinity.
This Interactive Online Mathematics Dictionary was developed for use by middle school mathematics students as well as the parents and teachers of middle school mathematics students. The language of the definitions attempts to be consistent with middle school levels of rigor. The examples, links, tests help to elaborate on the definitions. Although developed as a separate project, it was incorporated into the InterMath Project and has been adopted by the Georgia Department of Education.
Project InterMath was funded by the National Science Foundation as a collaborative effort of the Department of Mathematics Education and the Learning and Performance Support Laboratory (LPSL) and the CEISMC group at the Georgia Institute of Technology. InterMath is a professional development effort designed to support teachers in becoming better mathematics educators. It focuses on building teachers' mathematical content knowledge through mathematical investigations that are supported by technology. InterMath includes a workshop component and materials to support instructors.
Excellent site for History of Mathematics. Also, interactive Java graphs of many curves.
