This publication helps educators create differentiated reading instruction experiences for their students by showing the relationship between two distinct resources: Student Center Activities (SCA) and the Common Core State Standards (CCSS). Reading specialists, reading coaches, and teachers will find this document useful in lesson planning, as it contains crosswalks that map the relationships between each SCA and a corresponding, grade-specific standard in CCSS. The guide illustrates how SCAs relate to standards in English Language Arts and Literacy in History/Social Studies, Science, and Technical Subjects in K–5.
