The Thinking Behind the Content:
Standards for Mathematical Practice
in contending with difficulties.
– Abigail Adams
The Common Core State Standards for Mathematics have two sets of standards: the Standards for Mathematical Content and the Standards for Mathematical Practice. The content standards are different for each grade level and outline what students are expected to understand and be able to do at each grade. They are organized by domain or concept. Each domain includes related clusters of standards for each grade. The Standards for Mathematical Practice, however, are the same eight standards across all grade levels K12. As stated in the Common Core, they represent the “expertise that mathematics educators at all levels should seek to develop in their students.” In other words, they describe what it means to “do” mathematics and apply mathematical content. These standards represent the kind of thinking students do as they are learning the content and how we want them to engage with mathematics. Teachers have the challenge of planning for and teaching both the content standards and the Standards for Mathematical Practice.

Standards for Mathematical Practice

Principles Guiding the Implementation of
Standards for Mathematical Practice
The Standards for Mathematical Practice should be embedded in the Content Standards.
One way to assess students’ understanding of the content standards is through the practice standards. For instance, when asking students to apply the content learned
 Is the student able to justify why an answer is correct or a specific rule applies?
 Can the student approach a problem and determine a way to solve it?
 Can the student write equations or expressions relevant to a specific task?
 Does the student notice different patterns and structures embedded in problems?
Teachers must carefully analyze the tasks they are assigning and be intentional about which practice standards will be emphasized and where they will be emphasized.
The practice standards should not become lessons that are separate from the content expected at each grade level. Rather, the practice standards should be integrated with the content required in the content standards. The practice standards must be given the same care and attention as the content standards and not be an afterthought or assumed to be “always happening.” Rather, teachers must carefully analyze the tasks they are assigning and be intentional about which practice standards will be emphasized and where they will be emphasized. As suggested in Implementing the Common Core Mathematical Practices, one way for teachers to think about this is to look at each mathematical practice in relation to assigned tasks and consider the potential for students to be engaged in each practice: high, medium, or low. 
The Mathematical Practices are standards, and they require explicit teaching.
The Common Core is very clear in saying that these standards “are not intended to be new names for old ways of doing business.” They are designed to move us forward with a sense of urgency, towards more robust and lasting learning in mathematics. It is not enough to simply have them posted on the wall, or to say that they are happening all of the time in all lessons. If that were true, they would be occurring with no intention, purpose, or depth of learning. Instead, these practices need targeted and explicit instruction provided in the context of the content the students are learning.
Not every Standard for Mathematical Practice will be emphasized in every lesson.
In order for students to learn how to engage in the practice standards, teachers need to choose which practice standards will be emphasized during particular tasks. Then, teachers can “turn up the volume” on those practices by explicitly modeling them and sharing examples of how students are applying them when engaging with the content. It is simply not realistic to think that eight practices will be an area of focus in every lesson if we want our students to learn how to engage in the communication, representation, reasoning, and proof required in mathematics.
Relationships exist between the Standards for Mathematical Practice.
While listed as eight separate standards, connections exist between the practice standards. Some are more general than others and, therefore serve as overarching ideas.
 Making sense of problems and persevering in solving them (1) while attending to precision (6) is relevant in all problem solving situations and illustrates the overarching level of thinking our students need to do whenever they are engaging in mathematic al work. This involves:
 Finding a valid entry point
 Planning a pathway to a solution
 Monitoring thinking
 Relating situations to prior knowledge
 Communicating with others using clear mathematical language and precise answers that have been calculated efficiently and accurately
 Reasoning abstractly and quantitatively (2) and constructing viable arguments and critiquing the reasoning of others (3) focus on students’ skillfulness in
 Making sense of quantities and their relationships in problems
 Creating logical representations of problems
 Justifying thinking using mathematical ideas
 Proving the validity and reasonableness of answers
 Modeling with mathematics (4) and using appropriate tools strategically (5) encourage students in
 Simplifying problems
 Applying prior knowledge
 Representing the mathematics
 Using tools to help them visualize and solve problems
 Looking for and making use of structure (7) and looking for and expressing regularity in repeated reasoning (8) expect students to engage in
 Applying mathematical rules to specific situations
 Noticing generalizations and patterns.

In summary, the Standards of Mathematical Practice demand our attention and commitment. In order for our students to learn mathematical content at the depth expected in the Common Core, students need instruction in the practice standards as well. It is through these standards that students will develop the dispositions and ways of thinking that are the foundation of math learning.
In order to do this significant work, we need experience unpacking each Standard for Mathematical Practice and opportunities to explore each of them in the context of the content we are required to teach. In subsequent issues, we will dig deeply into some of these standards and illustrate what they look like in authentic learning situations.
