Good readers are engaged, active participants in the reading process–employing a variety of comprehension strategies while they are reading. The Common Core calls for close and analytical reading of challenging texts, and to be successful students must know how to monitor their own comprehension and what to do if that comprehension breaks down. During -reading lessons must provide initial instruction in how to monitor and correct comprehension as well as collaborative and independent practice with these strategies. Teachers might use these strategies in whole class, small group or one-on-one lessons.
