Illuminations
Here are 42 geometry lesson plans ranging from the geometry of computer animation to symmetry and conic sections.

Circle Packing
Geometrically determine the most efficient arrangement for pop cans, and investigate the concept of curvature.

To Fret or Not To Fret
Students will measure the distance between frets on stringed instruments to learn about geometric sequences.

Geometry Resources
While this site does not contain many projects, it does have a very comprehensive explanation of many geometry concepts, from beginner to extremely advanced.

Interactive Shapes
Here you will find interactive geometry tools. Check out the 3D Wire Frame page to show students three dimensional shapes.

HandsOn Geometry
This pdf file contains four lessons: mira constructions (lines and line segments), pythagorean puzzles, build a clinometer, and geometry flash cards. It is also available as an html file at http://mathcentral.uregina.ca/RR/database/RR.09.97/bracken1.html

eThemes Resource: Math: Geometry for Junior and High School
These sites have information on geometry for junior high and high school students. There are several interactive sites that allow the manipulation of geometric shapes. Also includes handson classroom activities and online quizzes. There are examples on how geometry is used in the real world such as geometric shapes in buildings and orienteering. There are links to eThemes Resources on mathematics in everyday uses and bridge construction.
