K–12 Session 4.1Standards for Mathematical Practices
Part 1: Making Sense of the Mathematics
Module 1:A Closer Look at the Common
Core State Standards for Mathematics
Expected Outcomes
• Build understanding of the standards for mathematical practice.
• Enhance skills in identifying the extent to which students exhibit the standards for mathematical practice.
• Generate ideas for how teachers can integrate the standards for mathematical practice with instruction to support student proficiency.
Principle #1: Increases in student learning occur only as a consequence of improvements in the level of content, teachers’ knowledge and skill, and student engagement.
Richard Elmore, Ph.D., Harvard Graduate School of Education
Principle #2: If you change one element of the instructional core, you have to change the other two.

Introduction to the CCSSM Standards for Mathematical Practices
Standards for Mathematical Practice
The Standards for Mathematical Practice 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.

NCTM Process Standards
• Problem Solving• Reasoning and Proof• Communication• Representation• Connections
11
The Standards for Mathematical Practice1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.

Matching a Graph to a Story

A. Tom took his dog for a walk to the park. He set off slowly and then increased his pace. At the park Tom turned around and walked slowly back home.

C. Tom went for a jog. At the end of his road he bumped into a friend and his pace slowed. When Tom left his friend he walked quickly back home.

B. Tom rode his bike east from his home up a steep hill. After a while the slope eased off. At the top he raced down the other side.

The rough sketch graph shown above describes what happens when 3 athletes A, B, and C enter a 400 meters hurdles race.
Imagine that you are the race commentator. Describe what is happening as carefully as you can. You need not measure anything accurately.

Small Group Discussion
• Form groups around pairs of math practices• Identify verbs used in the practice
• Questions:– What is this practice standard asking of students?– What would this practice look like in your classroom?
23
Whole Group Discussion
• On a scale of 1 (low) to 5 (high), with a show of fingers, to what extent is your school or district promoting students’ proficiency for this practice?
• To what extent is this practice being explicitly addressed in every classroom?
• How does understanding the context of the problem help engage students in the practice?
• What is challenging about helping students develop proficiency in this standard?
24
Reflection
• How do the standards for mathematical practices connect to what you know of past standards (e.g. NCTM & Adding it up) as well as what you know about best practices?
• What do you anticipate to be challenges in supporting students in developing proficiency in these practice standards? What actions will you take to address and overcome these challenges?
• How does addressing misconceptions and context help students engage in the mathematical practices?
• How has this activity increased your understanding of the instructional core?
