MAIN IDEA!!!! You have just finished reading a short story to your teacher. “Good reading!” she says. “What is the main idea?” You reply, “The main idea?” The teacher says, “Yes, what is the main idea of the story you read?” If you were stumped then about the main idea, or if you have EVER been stumped by that question, here is an idea that can really help you. The main idea is the main reason that the story was written. I’m sure you can tell me the main reason for lots of things...without even reading!
