This collection of online geometric teaching materials and lesson plans was assembled by David Eppstein, a professor in the Computer Science Department at the University of California, Irvine, and creator of the Geometry Junkyard (reported on in the June 9, 1999, Scout Report for Science & Engineering). This site offers links to an eclectic assortment of educational lessons and resources including a French geometry hypertext; a site with activities for middle school students based on M.C. Escher's artwork; an online book addressing dynamic software for geometry; a freeware geometric construction software for Windows (Wingeom); and a site containing cool geometric activities with Tangrams, Symmetry, Polygon Tessellations, Geoboards, and more. It should be noted, however, that links to some websites are not currently connected. Teachers, students, and others will also want to check out other sections of the Geometry Junkyard for more educational resources. Eppstein has organized geometry-related links by such topics as Origami, Geometric Models, Rectilinear Geometry, and Spirals, to name a few.
