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 SAT-Type 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; School-Bus Geometry (a non-Euclidean geometry introduced using a school bus rather than a taxicab; and Glossary of geometric terms. Includes Geometer's Sketchpad sketches to download. more>>

  6. GirlTECH - Cynthia Lanius; Center for Research on Parallel Computation (CRPC)
    GirlTECH was a teacher training and student council program that encouraged young women to pursue careers in mathematics and science, offering intensive technology training to explore innovative teaching strategies for gender equity in the classroom through a training period at The Rice School and Rice University in Houston, Texas. GirlTECH lesson plans were designed by participating teachers to take full advantage of Internet resources and teach standard concepts in mathematics and sciences in new and exciting ways. The site includes lessons and Internet projects from 1995-2006. more>>

  7. K-12 Teaching Materials (Mathematics Archives) - University of Tennessee, Knoxville (UTK)
    An extensive list of Internet sites with significant collections of materials that can be used in the teaching of mathematics at the K-12 level. Organized into categories: lesson plans, schools, software and other K-12 Internet math sites. more>>

  8. 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 in-service teachers of high-school 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. more>>
