Expressions and Equations: Another Common Core Learning Progression Released

The Common Core State Standards in Mathematics were built on progressions: narrative documents describing the progression of a topic across a number of grade levels. These documents were spliced together and then sliced into grade level standards. The Progressions Project is organizing the writing of final versions of the progressions documents for the K–12 Common Core State Standards. The work will be undertaken by members of the original work team of the progressions and also by mathematicians and educators not involved in the initial writing.

JUST RELEASED! The second DRAFT version of a progression has been released: Expressions and Equations. The project organizers welcome your feedback. Expressions and Equations tracks how these concepts articulate through grades 6-8 mathematics under the Common Core

Why should we examine and use this document?

1. We can all move towards greater coherence and focus by planning units and assessments in vertical teams. So, now we have a tool that helps us to examine how mathematical topics progress. We can use this tool to help ensure that all of our students progress coherently through Number and Operations in Base Ten in all grades K-5.
2. This document is in draft form. The authors are asking for math-educator feedback and input on this document. Your feedback will be used to shape the final version of this document (a document that will be used in at least 44 states in the US). Leave your comments in the discussion thread at the site above.

Hey, what about us?
Currently The Progressions Project has initial drafts for progressions on Operations and Algebraic Thinking, Number and Operations in Base Ten, Fractions, Geometry, Measurement and Data, and Statistics and Probability, and is having these reviewed. Stay tuned to Minds-on-Mathematics for the announcement that that other drafts have been released.
