# CT Common Core High School Math Standards

On July 7, 2010, the Connecticut State Board of Education adopted the new Common Core State Standards. While the Standards have yet to be implemented (and will most likely undergo further changes), what follows is a summary of the National and Connecticut State High School (9-12) Math Standards (broken down into common categories). These will be implemented statewide, including all of Fairfield County:

Summary

High School Standards: To practice applying mathematical ways of thinking to real world issues and challenges; to prepare students to think and reason mathematically, and to emphasize mathematical modeling for more real world applications.
