What do the details tell you more about? Explain that details come in different shapes and sizes Some details are things that happened in a story Other details are facts in an article When an author includes many facts, he or she is usually supporting an idea about a topic Order of Events Which events happened first? Which happened next? Which happened last? Tell students that some details tell about the order of events in a story or article Explain that being able to put the events in order can help readers better understand how one event leads to the next Main Ideas and Supporting Details Introduction In this lesson, you will learn how to find the main idea of a passage The main idea is what an article or story is mostly about You will also learn about details Supporting details tell more about a passage s main idea Imagine you tell a friend, I just a read a story about a robot who saves the world Guess what?
