All of California is beginning the transition from California State Standards to the Common Core Standards. 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".

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.
The Four Main Domains
The Common Core Mathematical Content Standards lay out the mathematics content that should be learned. The Standards do not dictate any particular scope and sequence. Mathematical content is organized in a number of domains. At each grade level there are several standards for each domain, organized into clusters of related standards.
There are four main domains to be taught from kindergarten to fifth grade:
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 answeroriented approach
 students being asked to explain their thinking
 an acceptance that there are multiple ways to solve the same problem
 students being asked to write about mathematics
 a shift toward openended questions and performance tasks with a limited focus on multiplechoice assessment

 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.

Mathematical content is organized in a number of domains. At each grade level there are several standards for each domain, organized into clusters of related standards.
There are four main domains to be taught from kindergarten to fifth grade:
 Operations and algebraic thinking;
 Number and operations in base 10;
 Measurement and data;
 Geometry.
