Rosenthal Prize Lesson — Sphere Dressing

The Museum of Mathematics has posted my Rosenthal Prize lesson, Sphere Dressing,  on their website and made it freely available for download.

In this lesson, students explore the connections between plane and solid geometry by designing and building hats to cover a sphere.  This set of activities, which includes options for grades 4 to 12, was part of my application portfolio for the 2012 Rosenthal Prize for Innovation in Teaching Mathematics , and I was honored to be named runner-up.  A nice profile of the two winners appears in Scientific American here.
