The Standards for Mathematical Practice
The 8 Standards for Mathematical Practice describe the behaviors of mathematically proficient students. Mathematics teachers at
all levels should seek to develop these behaviors. The practices rest on “processes and proficiencies” of longstanding importance in
mathematics education. These process standards and mathematical proficiencies represent the recommendations of the National
Council of Teachers of Mathematics and the National Research Council respectively.
Every lesson will include some of these practices although every practice may not be represented in every lesson. Student
behaviors are connected to teacher behaviors.
Practice #1 Make sense of problems and persevere in solving them
Students:

Analyze and explain the meaning of
the problem
