**Introduction to the Common Core**

The final version of the Common Core State Standards for Mathematics (CCSSM) was released by the Council of Chief State School Officers (CCSSO) and the National Governors Association (NGA) on June 2, 2010, the. As specified by the CCSSO, these standards are research- and evidence-based, aligned with college and work expectations, rigorous, and internationally benchmarked. While the CCSSM define what students should understand and be able to do in their study of mathematics, they do NOT dictate curriculum or teaching methods.

In the CCSSM, the following terms are used.

**Standards**define what students should understand and be able to do.**Clusters**summarize groups of related standards. Note that standards from different clusters may sometimes be closely related, because mathematics is a connected subject.**Domains**are larger groups of related standards. Standards from different domains may sometimes be closely related.

**Helpful Resources**

Critical Areas of Focus is a document from the Ohio Department of Education that describes the big ideas that educators can use to build their curriculum and to guide instruction.

Assessing Mathematical Understanding is a set of mathematics assessments for kindergarten and first-grade students that provides both cumulative data about students’ progress over time and in-depth diagnostic information. Aligned with the Common Core State Standards for Mathematics, it is intended as a tool to help teachers track student progress, identify particular difficulties, and generally inform instructional planning.

InsideMathematics has a wealth of videos and tasks aligned to the Common Core standards.

SEDL has created a series of support videos for the CCSSM. Each video focuses on one or more specific standards and usually includes examples/illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard. These are NOT intended to be guides on how to teach each standard, although the examples can be adapted for instructional use.
