Math Practices
Online Resources
The Standards for Mathematical Practice describe varieties of expertise
that mathematics educators at all levels should seek to develop in their
students. These practices rest on important “processes and
proficiencies” with longstanding importance in mathematics education.
The first of these are the NCTM process standards of problem solving,
reasoning and proof, communication, representation, and connections.
The second are the strands of mathematical proficiency specified in the
National Research Council’s report Adding It Up: adaptive reasoning,
strategic competence, conceptual understanding (comprehension of
mathematical concepts, operations and relations), procedural fluency
(skill in carrying out procedures flexibly, accurately, efficiently and
appropriately), and productive disposition (habitual inclination to see
mathematics as sensible, useful, and worthwhile, coupled with a belief
in diligence and one’s own efficacy).
