Common Core Focus of the Week: Rigor
Rigor is creating an environment in which each student is expected to learn at high levels, and each is supported so he or she can learn at high level, and each student demonstrates learning at high level. (Blackburn, 2008).

When creating Common Core - aligned lessons and activities naturally they will be correlated with particular standards, but it also important to address (in equal proportions) the three components of rigor: conceptual understanding, procedural skill fluency, and application. When examining lessons or even PARCC questions identify the component(s) of rigor that are meant to be addressed.
