Lesson Overview
Finding the Main Idea in Reading
The main idea is what a passage is mostly about — the central point that all the details support. Students often confuse the main idea with a single interesting detail. This lesson teaches students to ask ‘What is the whole passage about?’ rather than focusing on one fact, and to check that every detail in the passage connects back to that central idea.
The four-page lesson uses short reading passages followed by comprehension questions that ask students to identify the main idea and explain how supporting details relate to it. A complete answer key is included.
How to Use This Lesson
1. Introduce the concept of main idea vs. supporting details (page 1). Model the strategy: read the passage, then ask ‘What is this mostly about?’
2. Work through one passage together as a class (page 2). Have students highlight the main idea sentence and underline two supporting details.
3. Assign the remaining comprehension questions (pages 2–3) independently. Review answers using the key on page 4.
