What is the Common Core Standards? The Common Core State Standards
Initiative is a U.S. education initiative that seeks to bring
diverse state curricula into alignment with each other by following
the principles of standardsbased education reform. The initiative
is sponsored by the National Governors Association (NGA) and the
Council of Chief State School Officers (CCSSO).
The Mathematics Standards include Standards for Mathematical
Practice and Standards for Mathematical Content.
Mathematical Practice
The eight principles of mathematical practice are:
 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
Mathematical content is organized in a number of domains.
