I love working on outreach projects with children in K12, and for the general public through community fairs and talks.

With Sarah Hagen, David Pengelley, and Dan Rockwell I was involved in community fair math booths where people estimated Pi using the Buffon Needle Technique. See Sarah's website for some really cool math stuff, and a duet with a robot!

Along with Michael Renne, we developed activities for children that involved 3-D stereographic projections using spheres. The 3-D print design of these spheres were developed by the topologist Henry Segerman at Oklahoma State. With the help of engineer Sam Weiwel, we enlarged these spheres (see image on the bottom right). We have used these spheres in projects for 8th and 9th grade students, to help them understand mathematical concepts such as infinity. Segerman's demonstration video on YouTube is a must see!
