ABSTRACT
The Common Core State Standards for Mathematics are K-12 standards that illustrate the curriculum emphases needed for students to develop the skills and concepts required for the 21st century. This chapter describes two sets of standards: Standards for Mathematical Practice and Standards for Mathematical Content. Adopted by 45 states to date, the CCSS are organized into key content domains and articulated across all years of schooling and, when adopted, replace the existing state content standards. The new CCSS are evidence-based, aligned with expectations for success in college and the workplace, and informed by the successes and failures of the current standards and international competition demands. The new standards stress rigor, depth, clarity, and coherence, drawing from national and international studies such as the National Assessment of Educational Progress Frameworks in Mathematics and the Trends in International Mathematics and Science Study report in mathematics National Center for Education Statistics.
