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.
