This project develops images, extended examples, and principles that illustrate how the articulation, representation and justification of general claims about operations evolve in the elementary grades and how this work supports the transition from arithmetic to algebra in the middle grades. An online course uses the Sourcebook as a text to engage teachers in considering the underlying pedagogical and mathematical aspects of the work and implementing these ideas in their instruction.

The goal of this conference was to bring together classroom teachers, mathematics educators, mathematicians, and community college faculty to consider critical questions about content and pedagogy in the mathematics education of K-8 teachers. These discussions were grounded by co-teaching actual professional development sessions, through observing each other teaching, and through debriefing teaching sessions based on observations and videotape. The participants developed an emerging set of principles and approaches to professional development for K-8 teachers.

This project will develop and systematically investigate a teaching model to assist teachers in developing ideas about proof in grades 2-5. The teaching model provides both a tool for learning on the part of elementary teachers and a model of practice from which they can learn as they implement it.
