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.” (CCSS, 2010)

Standards for Mathematical Practice
1. 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.

Standards for Mathematical Practice
1. Individually review the Standards for Mathematical Practice.
2. Choose a partner at your table and discuss a new insight you had into the Standards for Mathematical Practice.
3. Then discuss the following question.
What implications might the Standards for Mathematical Practice have on your classroom?

Exploring QuadrilateralsDoing Mathematics
The kite manufacturer builds only quadrilateral kites, but it doesn’t make kites only according to the mathematical definition. The manufacturer can make any type of convex quadrilateral.
Manufacturer's Problem: Every time an order comes in, we need to figure out how to make that particular kite. This is not efficient.

Exploring Quadrilaterals Task as Set Up
1. In what ways could this instructional move support perseverance and/or precision within a problem solving context?
2. What might Ms. Humphreys achieve by incorporating this instructional move?
3. What other instructional moves did your facilitator model that supported perseverance and precision?
In the clips you watched during the task facilitation, Ms. Humphreys chose to be explicit about the “investigative process.”
![Page 15: 1 National Council of Supervisors of Mathematics Illustrating the Standards for Mathematical Practice: Problem Solving and Precision The National Council](https://reader035.vdocuments.site/reader035/viewer/2022062619/5516e82555034603568b47ef/html5/thumbnails/15.jpg)

Exploring Quadrilaterals Task as Enacted
1. What do you see or hear that indicates students are developing their abilities to persevere and use precision?
2. In what ways do perseverance and precision appear to be working in interaction to support problem solving?
3. What instructional moves or decisions that the teacher made appear to have supported these practices?
As you are watching the next video clips, consider the following:

Exploring Quadrilaterals Task as Enacted
1. How would you describe what Ms. Humphreys is doing in this clip?
2. Why might this be a productive instructional move to support problem solving and precision?
Ms. Humphreys opens the next class period by sharing samples of student work from the last class period. As she shares the student work, she comments on what she noticed while reviewing their work (e.g., thinking she saw methods students/groups used to communicate developing ideas).

Exploring QuadrilateralsImplications for Instruction
Take a few minutes to reflect on the instructional strategies discussed today.
1. Which of these strategies would you like to integrate into your own toolbox for instruction to promote problem solving and precision?
2. What could you do to prepare yourself and your students to interact with mathematics in similar ways?
