## K-12 mathematical practices

K-12 Mathematical Practices [processes and proficiencies] ought to engage with the subject matter as they grow in mathematical maturity and expertise throughout the school years.

- 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.

*Content related categories are labeled as**:*

## Conceptual categories K-8

- Counting and Cardinality (K)
- Operations and Algebraic Thinking (K, 1, 2, 3, 4, 5)
- Number and Operations in Base Ten (1, 2, 3, 4, 5)
- Number and Operationsâ€”Fractions (3, 4, 5)
- The Number System (7, 8)Measurement and Data (K, 1, 2, 3, 4, 5)
- Geometry (K, 1, 2, 3, 4, 5, 6, 7, 8)
- Ratios and Proportional Relationships (6, 7)
- Expressions and Equations (6, 7, 8)

- Functions (8)

## Conceptual categories for high school

- Number and Quantity
- Algebra
- Functions
- Modeling
- Geometry
- Statistics and Probability
- Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers) for advanced mathematics.

*There are no Perspective or Attitude (Habits of Mind) categories - except persistence is used in making sense and solving problems*
