What is Principles and Standards for School Mathematics?
NCTM previously released three volumes of Standards documents—Curriculum and Evaluation Standards for School Mathematics (1989), Professional Standards for Teaching Mathematics (1991), and Assessment Standards for School Mathematics (1995). These documents have greatly influenced the way we think about teaching mathematics. Principles and Standards for School Mathematics strengthens and extends the messages of the original Standards documents. It provides a vision for mathematics education built on high achievement for all students in the classroom. This document and the NCTM’s previous Standards make recommendations about what mathematics students should learn, what classroom practice should be like, and what guidelines can be used to evaluate the effectiveness of mathematics programs.
