Common Core Math Standards

The CCSS mathematics standards were developed by the National Governors Association Center for Best Practices (NGA Center) and the Council of Chief State School Officers (CCSSO) in collaboration with teachers, school administrators, and experts. These mathematics standards define the knowledge and skills students should have within their K-12 education.

Common Core State Standards

The Common Core State Standards provide a consistent, clear understanding of what students are expected to learn, so teachers and parents know what they need to do to help them.

Illustrative Mathematics

This site has tools and instructional materials that help you to better understand and implement the CCSSM. This site has been created through a collaboration of the Charles A. Dana Center at the University of Texas at Austin and Agile Mind with partial funding from the Bill & Melinda Gates Foundation.

The Mathematics Common Core Toolbox

Illustrative Mathematics provides guidance to states, assessment consortia, testing companies, and curriculum developers by showing the range and types of mathematical problems that students experience in a true implementation of the Common Core State Standards, and by publishing tools that support implementation of the standards. The Illustrative Mathematics website is an initiative of the Institute for Mathematics and Education funded by the Bill & Melinda Gates Foundation.

Tools for Common Core Standards

This is a blog that discusses news about tools that are being developed to support implementation of the Common Core State Standards. The blog is developed and moderated by Bill McCallum, PhD.

Smarter Balanced Assessment Consortium

The Smarter Balanced Assessment Consortium is one of the two state-led consortiums working to develop the next-generation assessments that will accurately measure student progress toward college- and career-readiness. Smarter Balanced is funded from the U.S. Department of Education develop an assessment system aligned to the Common Core State Standards by the 2014-15 school year.

The Partnership for Assessment of Readiness for College and Careers

The Partnership for Assessment of Readiness for College and Careers (PARCC) is a consortium of 23 states plus the U.S. Virgin Islands working together to develop a common set of K-12 assessments in English and math anchored in what it takes to be ready for college and careers.
