How to read this checklist
Each line starts with the official code. The sentence after it is our own description of what children do in the lessons; it is not the wording of the standard. Some standards are covered only in part, and the sentence tells you which part.
For the exact wording of each standard, see the official document: Common Core State Standards for Mathematics (2010)
