As part of its proposal to the U.S. Department of Education, the Partnership for Assessment of Readiness for College and Careers (PARCC) committed to developing Kindergarten through Grade 2 Model Content Frameworks for Mathematics (K-2 Model Content Frameworks) to serve as a bridge between the Common Core State Standards (CCSS) and the PARCC non-summative tools. The PARCC K-2 Model Content Frameworks are voluntary resources meant to be used as a companion to the Common Core State Standards to help educators and those developing aligned curricula and instructional materials. The frameworks help clarify the standards by illustrating how key content shifts from Kindergarten through Grade 2 coherently to Grade 3 and beyond. They also serve as an example of how teachers and curriculum writers may frame instruction using the standards across the academic year.
