This is a great way to introduce main idea. These lists are brief and to the point. The main idea is written in bold-faced and is accompanied by three supporting details. This document can be manipulated to meet the needs of your students. For example, you can change the main idea so it is not bold, jumble up the list, and have students work cooperatively to pick out the main idea. Or, separate the examples, paste them on note cards, and have students play "Quiz Quiz Trade." Students each have a note card and walk around the room until they find a partner. Each student quizzes the other about what the main idea is, the students trade cards, and find another partner. They repeat this procedure. A great activity!
