The Show-Me Center, located at the University of Missouri, is a math education project of the National Science Foundation. The center's Web site "provides information and resources needed to support selection and implementation of standards-based middle grades mathematic curricula." There are some sample lesson plans offered, but most of the material is solely for use by teachers. Five different middle grade math curriculums were started in 1992, and now, the implementation and results of each curriculum are presented on this site. Teachers can examine each one, view video clips, and read case studies and other reports to choose which parts of the curriculums would fit best into their own classes.
