Another learning progression has been released in draft form: Ratios and Proportional Reasoning in Grades 6-8. The Common Core authors have commented that this progression was particularly difficult to create because there is a lot of conflicting and confusing language about ratios and proportional reasoning out in the field. Because of the conflict, they struggled with decisions about the extent to which they should try to standardize the language. As a result, comments on this draft would be especially appreciated.
