If you have more time, or would like your students to practice previewing in more detail, have them follow this strategy which adds the introduction, topic sentences, the conclusion, and comprehension questions to their previewing. Here are some extended instructions you can give to your students:

1. Read the title.
2. Read the introduction.
3. Read each boldfaced heading. Then read and underline or highlight the first sentence under each heading. This first sentence often provides the main idea for the section.
4. Look at all of the pictures, including graphs and charts, and read their captions.
5. Read the conclusion.
6. Read the end-of-chapter questions to find out what the authors consider most important in the chapter.
