California math teacher: Common Core adds up

Recent events in the long pursuit of common ground with policymakers around support for Common Core has left me scratching my head and searching for answers. The reality is that too many state legislatures have disregarded over four years of impressive teaching and learning in our nation's schools.

Ensuring all students are prepared to succeed in college and career is at the heart of the Common Core State Standards. As teachers work hard to find ways to help all students reach these expectations, we’re working to ensure that there are high-quality instructional materials available that have been developed by teachers for teachers.

The Mathematics Design Collaborative (MDC) brings to mathematics teaching and learning high-quality instructional tools and professional support services that play a pivotal role in helping the Bill & Melinda Gates Foundation realize its ambitious goal of having 80% of low-income and minority students ready for college by 2025.
