During my first two years of grad school, I was an NSF graduate fellow through the GK-12 grant held here at U. Hawaii. I worked with both a Hawaiian immersion school Halau Lokahi and a more traditional public high school on island, Kailua High School. 
My favorite projects included teaching middle schoolers how to turn squares into spheres, mobius bands, and tori. I had high schoolers explore surfaces with connected and disconnected boundaries by cutting up large quantities of paper.
