About...

I hope that this page is useful to the people who find it. The files contained here were mostly produced for the high school classes that I teach. A few are the results of my own whimsical explorations, and may seem to have less of a bearing on a particular class or curriculum. Others are vastly overbuilt and include programming that you may think should have been done with Fathom or Excel or raw Java. Still others focus on a topic so narrow that it may be painlessly omitted from their respective course.

The common thread in all of these sketches (mixed metaphors aside) is that they are some of my best efforts to use technology in the expression of mathematics in my classroom. I spend a lot of preparation time immersing myself in the mathematics, and this usually involves Sketchpad, Excel, and a more primitive paper notebook. The result is typically a messy set of files that my students do not see, but occasionally the pictures evolve into something worth presenting to them.

There is some redundancy on this site; for example, the transformation sketch with sliders to control parameters of a quadratic function can be found anywhere there are GSP files. I do not mean to dilute the internet with what has already been done elsewhere. Rather, it has become clear to me that some of the topics I traffic are not well-represented on the internet, and I am interested in providing a handful of nice resources to begin filling that void.

This site is certainly not moving toward an exhaustive reference of lesson plans, but rather a disjointed sampling of those sporadically occurring explanations which are impossible to provide with a mere marker on a dry-erase board.
