NCTM San Diego
Presentation Summary
This is the summary of a presentation given at the 74th Annual NCTM Meeting, 25-28 April 1996, San Diego, CA.
Demonstrations of hands-on Geometry projects for the secondary classroom.Included will be:
- Tessellation Project. We will cover a basic definitioin, show how students work with regular polygons on desktops, show examples by Escher, and talk about how to make a tessellation.
- Sierpinski Pyramid. We will go through the steps of making a nine-and-one-half-foot tall structure. This might or might not be part of a classroom unit on fractals and chaos.
- Mobius strips. This is a short demonstration of some possible classroom activities, alon with a brief description of where in "real life" a person might see a Mobius strip.
- Snowflake Project. Step-by-step method of folding and cutting paper to form regular polygons, and a project that incorporates these into "snowflake designs."
- Hand-Drawn Fractals. If time permits, after a brief description of some characteristics of fractals, we will go through some possible hand-drawn fractals (Sierpinski gasket, Koch snowflake, Cantor set and one or two more), and show original creations done by students.
