Mathematics education for the 21st Century must be a rigorous approach that gives students a balance of conceptual understanding, procedural fluency, and the ability to apply what they have learned to novel situations. There is no shortage of resources out there to support teachers to accomplish these goals. However, the most important factor is the classroom experience of students.

The California Common Core State Standards capture the rigor that is required in this new era of math education. These standards that were adopted in 2010, if implemented well, will prepare our students to be college and career ready no matter the path they take.

Achieve the Core

This site provides free, high-quality resources for educators implementing the Common Core State Standards.

Illustrative Mathematics

Illustrative Mathematics illustrates the range and types of mathematical work that students experience via the Common Core State Standards and provides access to tools that support standards implementation.

Inside Mathematics

This site features classroom examples of innovative teaching methods and insights into student learning, tools for mathematics instruction that teachers can use immediately, and video tours of the ideas and materials on the site.

Mathematics Assessment Project (MAP)

The Mathematics Assessment Project is working to design and develop well-engineered assessment tools to support schools in implementing the Common Core State Standards.

Sense-Making in Mathematics

This website from Strategic Education Research Partnership (SERP) is a synthesis of conversations with teachers, videos of teaching mathematics, and curriculum recommendations for a more thinking-oriented rigorous approach to middle school mathematics.
