When you read a passage, it's important to figure out the main idea—the big picture of what the author wants you to know. The main idea is like the heart of a story or article, and the details support or explain it.
Details are the supporting facts, examples, or explanations that help you understand the main idea. They add color and depth, helping you remember and make sense of what you read.
The more you practice identifying main ideas and supporting details, the better you'll get at quickly understanding what you read.
Being able to spot the main idea and details helps you:
Reading a news article about recycling and identifying that the main idea is to encourage people to recycle more, with details about how recycling helps the planet.
Summarizing a story about a lost dog by pointing out the main idea (a dog's adventure to find its way home) and key details (the places the dog visited).
