4The consensus among educators nationwide is that in-depth instruction paired with focused assessment of essential concepts and skills are far more effective than superficially covering every concept and skill in the standards. Educators are faced with the task of teaching all standards while meeting the extraordinary range of student learning needs. Prioritizing the Common Core offers common sense solutions to the dilemmas teachers face today in implementing the new, more rigorous national standards. Chapters present a rationale for prioritizing the Common Core, a step-by-step process for prioritizing standards in language arts and mathematics, strategies for soliciting feedback and input from everyone in the district or school prior to the final determination of the Priority Standards, and detailed summaries of the process schools in six different districts used to identify their Priority Standards, with accompanying commentary by those who directed the work.
