About the Common Core State Standards in Mathematics

The Common Core State Standards (CCSS) for Mathematics are organized by grade level in grades K–8. At the high

school level, the standards are organized by conceptual category (number and quantity, algebra, functions,

geometry, and probability and statistics), showing the body of knowledge students should learn in each category to

be college and career ready, and to be prepared to study more advanced mathematics. The Standards for

Mathematical Practice describe ways in which developing student practitioners of the discipline of mathematics

increasingly ought to engage with the subject matter as they grow in mathematical maturity and expertise

throughout the elementary, middle and high school years.
