Use this lesson plan, mentor text suggestions, and PPT sold separately to teach your students how 'careful' readers identify the main idea of the books and articles they read.
The main idea table is a great visual that helps students understand the importance of 'supportiing' details.
The powerpoint is interactive and can be used alone as an introduction. This lesson plan can easily span several days or more. The main idea table is a graphic organizer that I have used successfully for the past 12 years.
Take this lesson a step further by having students write the main idea and supporting details from an article as an informational paragraph.
