A Snapshot of the Common Core Standards for Mathematical Practice
In addition to the content standards that state what students need to learn at each grade level, the Common Core Standards for Mathematical Practice describe how students should approach their mathematical work and what kinds of tasks teachers and curriculum should present to students.
You can use the following list to keep track of the eight Common Core Standards for Mathematical Practice. They are as follows:

Making sense of problems and persevering in solving them

Reasoning abstractly and quantitatively

Constructing viable arguments and critiquing the reasoning of others

Modeling with mathematics

Using appropriate tools strategically

Attending to precision

Looking for and making use of structure

Looking for and expressing regularity in repeated reasoning
