Common Core State Standards (CCSS) for mathematics are rigorous. Now that most states have accepted the CCSS, they need to first understand the CCSS and then design a way to implement the CCSS in mathematics. This third title in series discusses the rigor of the standards; reviews learning progressions; defines practice standards, and focuses on developing mathematical problems to create higher math development. Volume one is Navigating Implementation, volume two is English Language Arts and volume four is Assessment and Collaboration.
