The Common Core State Standards provide us with new levels of text complexity. On this site, the authors provide us with suggested texts for the high school grade levels:
What do you notice about this list?
Someone I was with recently noticed that the suggested texts don't align with a particular "curriculum:" they are a mixture of World Literature, American Literature, and British Literature.
This mixing leads me to believe that the student outcomes articulated about the Common Core can be reached with ANY text, so the traditional plan of studying literature in the old categories no longer exists! This realization might be a shock to the system, but it actually is freeing because teachers have more choices.
In short, enjoy teaching the texts you know, experiment with new texts, and keep the rigor high.
