The Common Core approaches the content areas (Social Studies and the Sciences) with a particular emphasis on literacy. This has several implications. First, note that literacy in the Common Core means listening and speaking as well as reading and writing. Audio files from the Library of Congress, for example, have an important role to play. Further, English Language Arts components of the standards incorporate numerical data, audio-visual, and digital information. Census and economic data, historic films, and survey data–all gain importance in the classroom.
