Reading Comprehension: Main Idea and Details
Main Idea and Details
Main Idea and Details
What you'll learn
- The main idea is what a passage is mostly about — its big picture message.
- Details are the small facts that support and explain the main idea.
- Good readers can tell the main idea apart from the smaller supporting details.
Key concepts
Level 1 — Finding the main idea
Ask yourself: "In one short sentence, what is this passage mostly about?"
Level 2 — Finding details
Details answer questions like who, what, when, where, and how many — they support the main idea.
Level 3 — Main idea vs details
| Main idea | Detail |
|---|---|
| Ravi's pets | He has a dog, two rabbits, and a parrot |
| A festival of lights | People light lamps and share sweets |

Common mistakes
| Mistake | Why it happens | Fix |
|---|---|---|
| Picking a detail instead of the main idea | Focusing on one small fact | Ask what ALL the sentences together are about |
| Choosing an idea not mentioned in the passage | Guessing instead of reading carefully | Only choose ideas that are supported by the text |
| Missing specific facts when asked for details | Reading too quickly | Reread the passage to find the exact fact asked |
Quick check
- Read a short paragraph from your reader and state its main idea in one sentence.
- Name two supporting details from that same paragraph.
- Stretch: Write a 3-sentence paragraph about your school day, then ask a friend to find its main idea.
Revision tip: After reading any passage, always ask "What is this mostly about?" before answering detail questions.
