    How do we introduce irrational numbers without simply telling students that they are irrationals?
    To improve mathematics achievement of U.S. students and to assure that "what and how students are taught should reflect not only the topics within a certain academic discipline, but also the key ideas that determine how knowledge is organized and generated within that discipline" are dual goals of the Common Core State Standards for Mathematics (CCSSI 2010, p. 3). My recent work with eighth-grade teachers, however, made me wonder how much support teachers actually receive to implement the Common Core (CCSSM) standards so as to be consistent with the goals and vision.
