    conicsThe CCSS call for lessons on conic sections – after many schools have stopped teaching them, at least in non-honors classes. So, I wanted a way to show students how these slices of cones are defined and where the parts of the equations come from. I got busy in GeoGebra, spending a weekend making sixteen applets. Check them out here.


    After teaching for 14 years, I now design curriculum and create digital and print instructional materials for high school and middle school math. I have also invented and am now marketing radian-scale protractors. Check out www.proradian.net! I'm very happily married and have 2 grown sons and a cat named Louie.
