Achieve the Core you can find a "Focus By Grade Level" document that outlines the major work for each grade level.
The Sonoma County Office of Education has compiled instructional resources for learning more about the CCSS in Mathematics.
The Illustrative Math website has performance tasks for grades K-12.
These Math Unit Frameworks were developed by the CCGPS to provide "models of instruction" designed to support teachers in the implementation of the Common Core. There are examples of curriculum maps as well as models of lessons for each grade level.
These curriculum modules on the EngageNY website provide curriculum frameworks, lessons and downloadable resources for mathematics across K-12.
This site provides videos on exemplary lessons integrating the standards for Mathematical Practice as well as tasks and assessment resources aligned to the Common Core.
Explore this site to learn more about the Common Core Standards for Mathematical Practice and how they can be connected to the content standards. Use the Illustrations on the site, centered on student dialogues, to see the Mathematical Practices (MPs) in action.
The Mathematics Assessment Project (MAP) site includes resources on tasks and lessons that support teachers in formative assessments. MAP is a collaboration between the University of California, Berkeley and the Shell Center team at the University of Nottingham.
Highlights of the Common Core State Standards in Mathematics
The Common Core State Standards (CCSS) define what students should understand and be able to do in the study of mathematics. Students who master the CCSS for mathematics will be prepared for college-level courses and possess the skills necessary for success in today’s workforce. Below you can download the CDE's "Highlights of the Common Core State Standards in Mathematics" that provides an overview of the key areas of focus.
