I created this document as a tool for students to become familiar with the CCSS 8 Mathematical Practices. I included visuals to represent and define the mathematical practice. I find this as a useful reminder of what I need to do as a teacher and provide opportunities to practice these skills but to also remind students what they need to do. I make copies and have students refer to these when working on math problems. There is also a kid-friendly version with "I Can" statements.
