One of the authors of the first draft of the standards (how accurate is this?)
Simple, but urgent in his address:
Focus. Strongly where the standards focus
Coherence. Think across grades and link to major topics within grades
Rigor. Require conceptual understanding fluency and application."

You've got to read this (blog entries, research, American educator article by that math professor). By teachers for teachers (description of voices of educators doing the work of the core).
