What is a Central Idea?

The central idea (also called the main idea) is the MOST important point the author wants you to understand. It's not just what the text is about - it's the main MESSAGE about that topic. Key details are the facts that support and prove the central idea!

Topic vs. Central Idea vs. Summary

TOPIC

What the text is ABOUT

1-2 words

Example:
"Recycling"

CENTRAL IDEA

The MAIN POINT about the topic

A complete sentence

Example:
"Recycling helps protect our environment."

SUMMARY

Central idea + key details in YOUR words

A short paragraph

Example:
"Recycling helps protect our environment. It reduces waste and saves natural resources..."

The Umbrella Model: Central Idea & Details

Central Idea:
The main point of the text
Key Detail 1
Key Detail 2
Key Detail 3

Key details "fit under" the central idea and support it!

Key Details vs. Minor Details

KEY Details

  • Directly support the central idea
  • Help prove or explain the main point
  • Would be included in a summary
  • The text would lose meaning without them

MINOR Details

  • Interesting but not essential
  • Don't directly prove the central idea
  • Would NOT be in a summary
  • The text still makes sense without them

Amazing Animal Adaptations

Animals have developed amazing adaptations to survive in their environments. For example, polar bears have thick fur and a layer of fat called blubber to stay warm in the freezing Arctic. Their white fur also helps them hide in the snow while hunting. In the desert, camels can go for weeks without water because they store fat in their humps. They also have special eyelashes that keep sand out of their eyes. Scientists study these adaptations to learn how animals survive. These adaptations show how animals have changed over millions of years to fit their homes perfectly.
