One of the aspects of the Common Core ELA that I find to be most challenging is the ability to plan units that bring together featured and supporting texts. A featured text is the text(s) that all students in the class read regardless of reading level. This text(s) is the heart and soul of the unit and should frame the culminating assessment. Supporting texts, on the other hand, help students practice certain skills, acquire helpful background knowledge, research a topic or, most importantly, forge connections with the ideas and elements found in the featured texts. These texts may be leveled and could vary depending on the student or situation.
