Other Resources

The links on this page lead to web-based resources we've found useful in our own explorations with and thinking about geometry in the middle grades.

Connecting Geometry is a professional development course designed for middle grades geometry teachers. The course is based at the University of Wyoming, and many of the materials related to the course are available on its website.
