CCSS Mathematical Practices
From Thinkmath
To emphasize the Mathematical Practices, the CCSS gives them their own distinct section, but they are not to be thought of as a separate skill set to be handled in special lessons or supplements. The intent is that these essential mathematical habits of mind and action pervade the curriculum and pedagogy of mathematics, K–12, in age-appropriate ways. This document interprets and illustrates each of the eight Mathematical Practices as they might be exemplified in grades K–5.
Each article begins with the title of a Mathematical Practice, as given in the CCSS, followed by part or all of the CCSS description of that standard. Omissions are made only when the original text is an elementary school example that needs no further comment or is explicitly about content that goes beyond elementary school. All omissions are indicated with ellipses (…).

- Make sense of problems and persevere in solving them
- Reason abstractly and quantitatively
- Construct viable arguments and critique the reasoning of others
- Model with mathematics
- Use appropriate tools strategically
- Attend to precision
- Look for and make use of structure
- Look for and express regularity in repeated reasoning
