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. (It 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, do one or more of the following: make a prediction; ask a question, clarify something you had misunderstood, 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 where you model your thinking as you interpret the text. - Provide the students with specific tasks to complete while they reread a section. - Review the text as a group after everyone has reread it. Numeracy Develop a 7-step math-enhanced lesson on Ohm s law and working with equations and variables. Develop a 7-step math enhanced lesson on calculating total resistance in circuits, and on working with reciprocal numbers, fractions, and addition.
