Here is a draft of a document by Jason Zimba describing structures in the content standards: CCSS Atlas (in docx format, here is a pdf of the same document). It incorporates some of Jason’s writings that I have posted before (e.g. the stuff about pinnacles, and the graphic of flows leading to algebra), but has a lot of new material as well. Well worth reading for those thinking about assessment and curriculum based on the standards.
