Alumni Reunion, Program
August 10-11, 2002

Title: Shapes and Numbers (Saturday, 9-11:30 AM)

Presenter: Philip Mallinson

Description:

Participants will explore polygons and polyhedra both from a geometric perspective and also a numerical point of view. What numbers make a triangle, a square, a tetrahedron, an octahedron? Where do these numbers come from and what do they tell us about the geometry of the corresponding shapes?

Title: Golden, Square Root of 2 and 1/4 Flowers: Understanding the irrational world of seeds and spirals. (Saturday, 12:30-2:00 PM)

Presenter: Michael Naylor

Description:

Explore the relationship between your favorite irrational numbers and their ability to describe matematically the growth form of objects in in the physical world.

Title: A Truncated Isocahedral Triangular hebesphenorotunda: (Saturday, 2:00-5:00 PM)

Presenters: Ronda Webber and Will Webber

Description:

Each participant will build a large triangular hebesphenorotunda. We will then assemble 20 of these regular faced polyhedra into a huge multi-holed troidal structure. The building process will be interlaced with discussions of the names involved, calculations to show existence, and general polyhedral theory to show where each of the polyhedra involved in the construction fits into the polyhedral theory. (This is an encore performance of a 1999 workshop.)

Title: Illuminate the Alumni This is you! (Saturday, 8:00 PM - ??

Our traditional sharing time with all participants. The theme this year is scoring, rubrics, and assigning grades to reflect attainment of learning targets. Please bring examples of projects and their rubrics along with grading ideas that show how students have attained standards.

Title: What's new from Park City Mathematics Institute? (Sunday, 8:30 -12:30 PM)

Subtitle: EITHER Math in Centers of Mass OR Rugby and Math

Presenter: Troy Jones

Description:
Either a hands-on exploration of the geometry of centers of mass or some surprising math in the the game of rugby.

Subtitle: Paper Plate Geometry

Presenter: Peg Cagle

Description:
Explore the relations inherent in proportional folding of the circle. Generate interesting patterns in two dimensions and astonishing structures in three dimensions.

Subtitle: Additional Ideas from PCMI

Presenters: The Park City Group (Art Mabbott, Joyce Frost, Carol Hattan, Gary Kovacs, Kris Koch, Brian Hopkins, Jim King)

Description:
The Park City Group will share a few new geometry activities that they will learn this summer at PCMI.
