Literacy
• Think Aloud & 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. (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
