Bring Geometry to Life with Google Sketchup


Google SketchUp is a free, fun, easy-to-use 3D modeling application. Originally created for architects and designers, SketchUp is also a great tool for teaching geometry.

3DVinci, hosted by the Math Forum, offers resources to help you do just that:

  • Projects of the Month
  • videos
  • teacher resources and guide
  • 2D and 3D project books
  • blog
  • geometry tips and projects
  • SketchUp Training Videos: Google-produced videos on SketchUp, from getting started through advanced topics
  • forums and discussion groups

"The Tiles of Infinity"


Peter J. Lu's trip to Uzbekistan inspired him to learn about Islamic tile patterns—and their surprisingly modern mathematics. Lu's photographs and diagrams illustrate this article by Sebastian R. Prange, from the September/October 2009 issue of magazine Saudi Aramco World.
