Literacy • Think Aloud and Say Something: Use as during-reading strategies. Take time when doing the Think Aloud to reflect on how it is you yourself make meaning when reading challenging trade-related text. Before assigning the Say Something, take time to model the strategy with a student or colleague and review the rules that will make for a successful Say Something. Iit is a good idea to post these rules so everyone can see them and be reminded of them during the activity: - With your partner decide who will say something first. - When you say something, make a prediction, ask a question, clarify something you had misunderstood, or make a connection. - If you cannot do one or more of the above things, then you need to reread. • Rereading: Use as a during-reading strategy. “Rereading is probably the number one strategy independent readers use when something stumps them in a text. It’s probably the last strategy dependent readers use.” (Kylene Beers). Before asking students to reread a section of text, you must first set the activity up for success: - Prove to students that rereading is valuable to their learning. You can model this while doing a Think Aloud (model your thinking as you interpret the text, taking time to reread a particular section. - Provide the students with specific tasks to complete while they reread a section). Review the text as a group after everyone has reread it.
