Progression on Ratios and Proportional Relationships

Here is a draft of the Progression on Ratios and Proportional Relationships. This one took a long time because there is a lot of conflicting and confusing language about ratios and proportional reasoning out in the field, and we struggled with decisions about the extent to which we should try to standardize the language. So comments on this draft would be especially appreciated. [Corrected file uploaded 13 February 2012]

Drafty draft of Fractions Progression

Here is an early draft of the progression for Number and Operations—Fractions. Unlike the other drafts I have posted, this one does not yet incorporate all the feedback we got from initial review, so more than usual I am interested in your comments. In particular I would like to know if it is too dense and needs more explanation, or if it is just right.

If you are reading it with Adobe Acrobat, you will need the latest version (10.1). If you are using a Mac, you can also use the native Mac pdf reader Preview, or the open source pdf reader Skim.

We hope to get drafts of the remaining K–8 progressions out soon; thank you for your patience.

The data part of the Measurement and Data Progression

We decided to combine the geometric measurement part of the MD Progression with the Geometry Progression (coming soon!). Here is a draft of the data part of the MD Progression (covering both categorical and measurement data): ccss_progression_md_k5_2011_06_20.

We will be releasing a draft of the Fractions progression before the end of June, and the Ratios and Proportional Relationships progression in early July.

Draft progression on Counting and Cardinality and Operations and Algebraic Thinking (K–2)

We have combined the Kindergarten Counting and Cardinality Progression with the K–5 Operations and Algebraic Thinking Progression. Here is the first half, ccss_progression_cc_oa_K2_2001_05_08, going as far as Grade 2. As usual, comments welcome on this thread. Grades 3–5 will follow soon.

Draft of progression on Number and Operations in Base Ten

Here is the first public draft of the progressions project, on Number and Operations in Base Ten [corrected version uploaded 26 May 2012]. We welcome any comments or suggested changes, which will be considered for the final draft. Please post comments to this thread. We will be releasing other draft progressions for elementary and middle school over the coming weeks.
