Main idea is the most important thought or message that an author wants to share in a passage, paragraph, or text. It tells what the text is mostly about.
The main idea is like the “big picture.” Details give clues to help you figure it out.
To find the main idea, ask yourself: “What is this text mostly about?” Then look at the details that support the answer.
The main idea is usually supported by details, but it is not just one detail—it’s the overall point.
Supporting details are the facts, examples, or descriptions that explain and prove the main idea.
Supporting details are like building blocks—they hold up and prove the main idea.
In nonfiction, the main idea often explains facts or teaches information. In fiction, the main idea may tell the lesson, theme, or what the story is mostly about.
Pay attention to whether you are reading a story (fiction) or facts (nonfiction)—the main idea will look different.
Use these strategies when reading to help identify the main idea quickly and clearly.
If you can explain the passage in one clear sentence, you have found the main idea.
