Have you ever been asked to find the main idea of something you read? This is a way to check if you really understood the text. The main idea is the most important point the author wants you to know, and you can usually say it in just one sentence.
When you’re reading an informational text, look for clues that help you find the main idea. Think about what type of text it is, why it was written, and what features it has. Informational texts give you facts about a specific topic. They can be reports, explanations, instructions, or descriptions. These texts are nonfiction, which means they are based on real information. Examples include articles, letters, textbooks, and essays.
Informational texts often start with a paragraph that introduces the topic and the main idea. They usually end by repeating this information. The paragraphs in the middle are called body paragraphs. Pay close attention to the first and last sentences of these paragraphs because the main idea is often found there.
Another way to find the main idea is to look for words like “but,” “even if,” or “in contrast.” These words show that the author is changing or adding to an idea. If you see these words at the beginning of a sentence, the main idea might be in that sentence instead of the first one.
Try scanning the text, which means quickly looking over it without reading every word. Look for titles, headings, pictures, and graphs. These can give you hints about the main idea. Also, watch for key words or synonyms that are repeated, as they might point to the main idea.
While scanning, try to guess what type of text it is, what it’s about, and why the author wrote it. In a test or assignment, you might need to find details like evidence, facts, and examples that support the main idea. These details are usually in the body paragraphs and help explain or describe the topic. They might also be shown in graphs, diagrams, or pictures.
Scanning helps you find these details, but you need to read carefully to make sure you have the right examples. To see how the details support the main idea, highlight sentences with evidence, facts, or examples, and then write down the idea they support in one sentence. This can help you understand how everything fits together.
If you’re still not sure about the main idea, try asking yourself questions to help you understand better. This can clear up any confusion you might have.

[Narrator] You may have been asked in a test or assignment to identify the main idea of an informational text or paragraph. This is done to ensure you understood what you read. The main idea is the most important point or key thought that the author wants you to know, and it can usually be expressed in just one sentence.
To find the main idea in an informational text, look for clues or evidence while reading. Considering the text type, its purpose, and its typical features can be helpful. Informational texts provide readers with information about a specific topic and include reports, explanations, procedures, recounts, and descriptions. They are nonfiction texts, such as articles, letters, textbooks, emails, instructions, or essays.
Informational texts typically start with a paragraph that introduces the topic and main idea, and they conclude with a restatement of that information. The paragraphs in between are called body paragraphs. Pay attention to the first and last sentences of each body paragraph, as the main idea is often explicitly stated there.
Another strategy is to look for conjunctions, such as “but” or “even if,” or phrases like “in contrast.” These words indicate that the author is going to modify an already stated idea. When these types of words begin the second sentence of a paragraph, there’s a good chance that the second sentence, rather than the first, contains the main idea.
Scanning the text—quickly running your eyes over it without closely reading—can also help you find the main idea. Look for features like titles, headings, images, and graphs that provide information about the topic and may point to the main idea. Examine each part of the text for key words and synonyms that are repeated, as they might indicate the main idea.
While scanning, try to predict the type of text, its subject matter, and the author’s purpose. In a test or assignment, you may be asked to identify details, such as evidence, facts, and examples that support the main idea. In informational texts, these supporting details are found in the body paragraphs and help describe, explain, or evaluate the topic. They may also be presented as graphs, diagrams, or illustrations.
A quick scan will help you locate this content, but careful reading is necessary to ensure you have identified the correct examples. To see how the details support the main idea, highlight the sentences that contain evidence, facts, or examples, and then write down the idea they support in a sentence. Visualizing this relationship can be helpful.
Finally, if you try these strategies and the main idea is still unclear, consider asking yourself specific questions to clarify your understanding.
