JUST RELEASED! The first DRAFT version of a progression has been released. Number and Operations in Base Ten tracks the conceptual and procedural development of numbers and operations from grades K-5.
Why should we examine and use this document?
- 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.
- 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.
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.
