In June 2010, the National Governor's Association and the Council of Chief State School Officers published "Common Core State Standards" (CCSS) for K-12 mathematics. Forty-eight states collaborated in the development of CCSS and, to date, 34 states have officially adopted CCSS to replace existing state standards. CCSS presents an opportunity for critical stakeholders to focus on curriculum as a means of improving teaching and student learning. In order to help state and local school systems design thoughtful curriculum guides and select instructional materials (text, e-text, and ancillaries) that are essential supports for implementation of the CCSS, it is necessary to connect those who have constructed the "Common Core State Standards" in mathematics with those members of the educational community who are expert in designing, developing, and implementing mathematics curriculum resources and instructional programs. Collaborations across these communities will help identify the work that needs to be done to provide strong resources for the field in the future. Therefore, a meeting of key stakeholders was convened August 1-3, 2010 to discuss curriculum-related work needed in response to the "Common Core State Standards for Mathematics." The goals of the meeting were to: (a) provide guidance on future mathematics materials development efforts, K-12, and (b) address issues of curriculum design and production that arise in an environment of Common Core State Standards. This report serves as a public dissemination of conference discussions, recommendations, and items for action. (Contains 2 figures and 3 footnotes.)
