For the new Common Core State Standards that will be effective in all North Carolina schools in the 2012-13.
This document is designed to help North Carolina educators teach the Common Core (Standard Course of Study). NCDPI staff are continually
updating and improving these tools to better serve teachers.
What is the purpose of this document?
To increase student achievement by ensuring educators understand specifically what the new standards mean a student must know,
understand and be able to do. This document may also be used to facilitate discussion among teachers and curriculum staff and to encourage
coherence in the sequence, pacing, and units of study for grade-level curricula. This document, along with on-going professional
development, is one of many resources used to understand and teach the CCSS.
What is in the document?
Descriptions of what each standard means a student will know, understand and be able to do.
The “unpacking” of the standards
done in this
document is an effort to answer a simple question “What does this standard mean that a student must know and be able
to do?” and to
ensure the description is helpful, specific and comprehensive for educators.
How do I send Feedback?
We intend the explanations and examples in this document to be helpful and specific. That said, we believe that as this document is used,
teachers and educators will find ways in which the unpacking can be improved and made ever more useful.
Please send feedback to us at
[email protected]
or

and we will use your input to refine our unpacking of the standards.
Thank You!

Standards for Mathematical Practice in Second Grade
The Common Core State Standards for Mathematical Practice are practices expected to be integrated into every mathematics lesson for all students
Grades K-12. Below are a few examples of how these Practices may be integrated into tasks that Grade 2 students complete.
1)
Make Sense and
Persevere in Solving
Problems.
Mathematically proficient students in Second Grade examine problems and tasks, can make sense of the meaning of the
task and find an entry point or a way to start the task. Second Grade students also develop a foundation for problem
solving strategies and become independently proficient on using those strategies to solve new tasks.
In Second Grade,
students’ work
continues to use concrete manipulatives and pictorial representations as well as mental mathematics.
Second Grade students also are expected to persevere while solving tasks; that is, if students reach a point in which they
are stuck, they can reexamine the task in a different way and continue to solve the task. Lastly, mathematically
proficient students complete a task by asking themselves the question, “Does my answer make sense?”
