Teacher’s Guide
Common Misconceptions:

- Students might list details without connecting them to the main idea.
Scaffolding Ideas:
For Struggling Students:

For Advanced Students:
- Challenge them to find multiple main ideas in longer texts.

- Encourage writing a short summary using main ideas and details.
Pacing Recommendations:
- Spend about 10-15 minutes reading and discussing the text.
