**Common Core Math**

The goal of the common core mathematics standards is to achieve greater focus and coherence in the curriculum. This is largely in response to the criticism that American mathematics curricula are "a mile wide and an inch deep".

**Parents may notice:**

- a greater emphasis on contextualized problem solving in lieu of repetitive (and decontextualized) skill practice.
- fewer, but "bigger" problems assigned
- an emphasis on mathematical reasoning over an answer-oriented approach
- students being asked to explain their thinking
- an acceptance that there are multiples ways to solve the same problem
- students being asked to write about mathematics
- a shift toward open-ended questions and performance tasks with a limited focus on multiple-choice assessment

The Mathematical Practice Standards

The Common Core Standards include Standards for Mathematical

**Practice**

*and*Standards for Mathematical

**Content**.

The Mathematical Practice Standards mandate that eight principles of mathematical practice be taught in every grade from kindergarten to twelfth grade.

- 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.
