Main Idea | Mini Lesson
Students will learn how to identify the main idea of a short reading passage and support it with key details. The lesson uses direct instruction, guided practice, and a quick independent application.
| Term | Definition |
|---|---|
| Main idea | The most important point the author wants the reader to understand. |
| Supporting details | Facts, examples, or reasons that explain or prove the main idea. |
| Topic | The general subject of a text. |
Display a short paragraph and ask, 'What is this mostly about?' Briefly introduce the term main idea.
Respond orally and share first impressions about the paragraph.
Explain the difference between topic, main idea, and supporting details. Model how to ask, 'What is the author saying about the topic?' and underline key details.
Listen, follow along, and mark important words in the model text.
Read a second short passage aloud. Guide students to identify the topic, then work toward the main idea using two or three supporting details.
Discuss answers with a partner and record the main idea on the organizer.
Give students a new short paragraph to read independently and identify the main idea and one supporting detail.
Work quietly and complete the task on their own.
Call on a few students to share answers and clarify any confusion.
Share responses and compare ideas with the class.
Ask students to finish the sentence: 'The main idea is...' and remind them to look for what the text is mostly saying, not just the topic.
Choose a short article, paragraph, or textbook section at home and write the main idea plus two supporting details.
