 CIESE Online Classroom Projects  Stevens Institute of Technology
Projects that use realtime data available from the Internet, and collaborative projects that use the Internet's potential to reach peers and experts around the world. The site lists currently sponsored projects by level, with an archive of past sponsored projects, each with a brief desciption and links to the National Science Standards and NCTM math standards it supports. Also at http://www.ciese.org/currichome.html. From the Center for Improved Engineering and Science Education (CIESE) at Stevens Institute of Technology.

 Geometry Online  Cynthia Lanius
Geometry activities from a geometry class at Milby High School in Houston, Texas. Topics include: History of Geometry (contributions of Egyptians, Babylonians, and Greeks, with links to biographies of major contributors to geometry); Hidden Polygons (locate them on triangular grid paper); Isosceles Triangle Puzzler (use the Isosceles Triangle Theorem to analyze a problem with similar triangles  answers can be submitted online); Circles and Pythagoras; an SATType Quiz (graded online); The Golden Ratio (do a measuring activity and build a rectangle that approaches the golden ratio; Experiment with Volume (demonstration of volume of cylinders; SchoolBus Geometry (a nonEuclidean geometry introduced using a school bus rather than a taxicab; and Glossary of geometric terms. Includes Geometer's Sketchpad sketches to download.

 Math 5337: Technology in the Geometry Classroom 
Sullivan, Burgiel, Osinga; The Geometry Center, Univ. of Minnesota
From the University of Minnesota's course in Computational Methods in Elementary Geometry, materials developed at the Geometry Center for teaching pre and
inservice teachers of highschool geometry interested in using technology in their classrooms. Internet skills: introduction to the Web, technical information; Classical Geometry: Introductory Questions for Geometer's Sketchpad; Monge's Theorem (Sketchpad lab); Peaucellier's Linkage (a simple toy). A Dynamical Systems lab uses Java applets; Symmetry and Patterns offers units on Introduction to Symmetries, Wallpaper patterns, and Orbifolds. With appendices (materials used in class, videotapes shown in the course); Software; and student projects: Napoleon's Theorem, Tessellations, the Golden Rectangle, Fibonacci Numbers, a Slice of Pi, Pascal, and Conjectures in Geometry. Most projects include several Geometer's Sketchpad sketches.

 Resource Room (Math Central)  University of Regina, Regina, Saskatchewan, Canada
French version: Centre de ressources. A service of Math Central that allows mathematics educators to share resources having to do with math teaching. Submissions are stored in a database that can be browsed by educational level and curriculum strand, or searched by keyword. Also: mathematics glossaries, sites of particular interest to Saskatchewan teachers, and a CyberBibliography. Elementary, middle, and secondary level strands include: algebra, calculus, data management and analysis/consumer mathematics; equations and problem solving; functions; general; geometry; math history; measurement; numbers and operations; problem solving; ratio and proportion; subject integration; and trigonometry.

 This is MegaMathematics! (MegaMath)  Nancy Casey; Los Alamos National Laboratory
The frontier of mathematics is an exciting place, where mathematicians experiment and play with creative and imaginative ideas, many of them accessible to young children; others (infinity is a good example) whose profound mathematical importance is not widely known or understood. MegaMath is a project of the Computer Research and Applications Group at Los Alamos National Laboratory intended to bring unusual and important mathematical ideas to elementary school classrooms so that young people and their teachers can think about them together.

 A Tour of Fractions  Math Forum
The Web often seems more like a maze than an organized set of resources. To help you find what you need, the Math Forum presents a 'tour' of fractions, offering links to lessons, activities, and materials, questions and answers from Ask Dr. Math, and recommended software, grouped by level (elementary, middle school, high school). Material on fractals is included.

 A Tour of Measurement  Math Forum
A central resource for people teaching and learning about measurement. For teachers there are links to lessons and materials, questions and answers from Ask Dr. Math, and recommended software, grouped by level (elementary, middle school, high school). For students there are general reference materials and questions and answers from the Dr. Math archives.
