National Mathematics Standards Categorized by process,
knowledge, attitude, and perspective:
PROCESS and INQUIRY KNOWLEDGE
Or
Practices and process skills:
the system of actions and procedures used to create knowledge
in the subject or discipline.
Or the practices of the discipline.

Problem Solving
 build new mathematical knowledge through problem solving;
 solve problems that arise in mathematics and in other contexts;
 apply and adapt a variety of appropriate strategies to solve problems;
 monitor and reflect on the process of mathematical problem solving.
Reasoning and Proof
 recognize reasoning and proof as fundamental aspects of mathematics;
 make and investigate mathematical conjectures;
 develop and evaluate mathematical arguments and proofs;
 select and use various types of reasoning and methods of proof.
Communication
 organize and consolidate their mathematical thinking through communication;
 communicate their mathematical thinking coherently and clearly to
peers, teachers, and others;
 analyze and evaluate the mathematical thinking and strategies of others;
 use the language of mathematics to express mathematical ideas precisely.
Connections
 recognize and use connections among mathematical ideas;
 understand how mathematical ideas interconnect and build on one another
to produce a coherent whole;
 recognize and apply mathematics in contexts outside of mathematics.
Representations
 create and use representations to organize, record, and communicate
mathematical ideas;
 select, apply, and translate among mathematical representations to
solve problems;
 use representations to model and interpret physical, social, and mathematical
phenomena.

CONTENT KNOWLDEGE
 the ideas (facts, concepts, generalizations, conjectures, theorums, and
proofs) that are created by doing the subject. 
Number and Operations
Algebra
Geometry
Measurement
Data Analysis and Probability 
PERSPECTIVE  the
relationship of the different dimensions of a subject or discipline to its
other dimensions and to its whole as well as the subject's or discipline's
relative significance for explaining and understanding the world. 
Connections (connections
are included in both the perspective and process skills categories. The
ideas expressed in these statements describe perspectives of mathematics
and are written as skills in their identification and use.
 recognize and use connections among mathematical ideas;
 understand how mathematical ideas interconnect and build
on one another to produce a coherent whole;
 recognize and apply mathematics in contexts outside
of mathematics.

ATTITUDE  The
diposition and values that people have that increase their likelihood
of success in the subject or discipline. 
The inclusion of disposition and value
statements in the principles, beliefs, and other supporting information
in the standards. Such as, become independent learners with a disposition
and capacity to engage in and value mathematics in their everyday lives.
