PCMI Notes

octahedron

In July 2006, I attended the Park City Mathematics Institute.
In the morning sessions for secondary school teachers, among many interesting activities, we used interactive geometry software to look at some good problems selected and organized by Bowen Kerins. Some of my work in that class:
Looks Isosceles!
Parallelogram Area
I also did a five-minute presentation on a geometry-graphing connection (Lab Gear and graphical representations of y=x^2+bx+c). Download:
geometry-graphing-connection.pdf
(The PDF is adapted from my book Algebra Lab Gear: Algebra 1, available from Didax.)
In the afternoon, I attended a course on knot theory, taught by the amazing Colin Adams. One outcome was this worksheet that should be ready to test with high school students:
Knot Theory (PDF)

Twice, in the evening, I led a Zome workshop.
