Distinguishing Topic from Main Idea

Mr. Ornelas teaches fourth graders how to determine the topic and main idea in a text. He explains that the topic is what the text is mostly about, while the main idea is what the author wants the reader to learn about the topic. Using the example of the invention of potato chips, he demonstrates how to identify repeating words to find the topic and how to use clues to determine the main idea. The lesson concludes with a discussion on differentiating between the topic and the main idea.
