**California Common Core Mathematics Standards **

The California Common Core State Standards: Mathematics reflect the importance of focus, coherence, and rigor as the guiding principles for mathematics instruction and learning. These standards demonstrate a commitment to providing a world-class education for all students that supports college and career readiness and the knowledge and skills necessary to fully participate in the twenty-first-century global economy. The Common Core math standards include two types of standards (seen in the images below):

**Eight Mathematical Practice Standards**(identical for each grade level) and**Mathematical Content Standards**(different at each grade level).

Together these standards address both “habits of mind” that students should develop to foster mathematical understanding and expertise and skills and knowledge—what students need to know and be able to do. The mathematical content standards were built on progressions of topics across grade levels, informed by both research on children’s cognitive development and by the logical structure of mathematics. The Standards for Mathematical Practice (MP) are the same at each grade level, with the exception of an additional practice standard included in the CA CCSSM for higher mathematics only: MP3.1: Students build proofs by induction and proofs by contradiction. CA This standard may be seen as an extension of Mathematical Practice 3, in which students construct viable arguments and critique the reasoning of others. Ideally, several MP standards will be evident in each lesson as they interact and overlap with each other. The MP standards are not a checklist; they are the basis of mathematics instruction and learning.
