Standards for Math Practices
The Standards for Mathematical Practices describe varieties of expertise that mathematics educators at all levels should seek to develop in their students. These practices rest on important "processes and proficiencies" with longstanding importance in mathematics education (National Governors Association Center for Best Practices, Council of Chief State School Officers, 2010).
If you search Standards for Math Practices, you will find many resources to support classroom teachers as they infuse the practices into their daily instruction. Inside Mathematics is one such professional resource available to teachers wanting to implement increased math learning and student performance. This site features video of classroom examples for each standard for math practice as explained in the common core.
