1.Do I routinely provide opportunities for my students to share their solutions and processes with partners, groups, and the whole class? 2.Do I show my students that I not only value process and the correct answer, I also value “what”, and “how” they are thinking because I always ask “why”? 3.Do I pose problems that require perseverance? Do I use thoughtful questions to guide and encourage students as they struggle with problems? 4.Do I routinely think aloud to show students how to change course when needed during the problem solving process? Developing Standard 1 Reflection Questions

“Putting the Practices into Action” “The Mathematical Practices explore and explain the habits of proficient mathematicians, and when we perform any task, particularly one as complex as math, our actions can not be simplified into compartments. Each standard has a unique focus, but each standard also intermingles with the others as we put it into practice. Rather than trying to compartmentalize these Practices, think about blending the Practices to empower your students to use math and to think mathematically.”
