OREO is a simple structure for opinion writing: Opinion, Reason, Example, Opinion. It helps a writer make a clear claim, explain the thinking behind it, support it with a detail, and end by restating the main idea. This structure matters because readers need to know what you believe and why they should take it seriously.
It is especially useful for short opinion paragraphs, quick writes, classroom responses, and persuasive writing practice.
The first O states your view in a direct sentence, such as School should start later. The R gives the reason behind that view, so the reader understands your logic before seeing support. The E adds an example, fact, detail, or piece of evidence that makes the reason stronger.
The final O returns to the opinion in fresh words, giving the paragraph a clear and confident ending.
Understanding ELA: How to structure opinion writing (OREO)
A strong opinion paragraph works because each sentence has a job. The opening claim gives the paragraph a direction. The next sentences must stay connected to that direction.
If a writer says that recess should be longer, then a reason about students needing movement fits. A detail about the color of the playground does not fit unless it proves something about movement or learning. This connection is called relevance.
Before adding a sentence, writers should check whether it helps prove the main claim. If it does not, it may distract the reader.
Reasons need more than personal preference. A sentence such as "I think it is better because I like it" repeats the opinion without explaining it. A useful reason shows an effect or result.
For example, later school start times can help students get more sleep. The explanation can go further by linking sleep to attention, mood, or learning. This shows the reader how one idea leads to another.
Words such as because, since, and therefore can make this logical link easier to follow. Writers should be careful not to make claims that are too broad. Saying that every student learns the same way is usually not accurate.
Examples are strongest when they are specific and believable. A personal experience can work when it clearly supports the reason. A student might describe feeling more focused during first period after getting enough sleep.
Facts from a class text, survey, article, or trusted school source can provide stronger support when available. Evidence should be explained, not dropped into the paragraph by itself. After giving a fact or example, the writer should state what it proves.
This is important because readers may not make the connection on their own. One clear example explained well is often better than several vague examples.
The final sentence should feel finished without copying the first sentence word for word. It can show the larger importance of the claim. A paragraph about later start times might end by stressing that rested students are better prepared to learn.
This ending reminds the reader of the main point while showing why it matters. During revision, read the paragraph slowly and listen for repeated words, missing links, or sudden topic changes.
Check that the reason actually supports the opinion and that the example supports the reason. This habit helps students write clearer responses in language arts, science explanations, social studies arguments, and everyday messages where they need to justify a choice.
Key Facts
- OREO = Opinion, Reason, Example, Opinion.
- O1 = state your view clearly at the start.
- R = explain why you hold that view.
- E = give evidence, a fact, or a specific example that supports the reason.
- O2 = restate your opinion in a new way to close the paragraph.
- Strong opinion paragraph = claim + reason + support + conclusion.
Vocabulary
- Opinion
- An opinion is a belief or view about a topic that can be supported with reasons.
- Reason
- A reason explains why the writer believes the opinion is true or important.
- Example
- An example is a specific detail, fact, story, or piece of evidence that supports a reason.
- Restate
- To restate means to say the same main idea again using different words.
- Persuasive Paragraph
- A persuasive paragraph tries to convince the reader to agree with the writer's opinion.
Common Mistakes to Avoid
- Giving the example before the reason is wrong because the reader needs to understand your logic before seeing the supporting detail.
- Writing an opinion that is too vague is weak because a sentence like School is good does not clearly show what you want the reader to believe.
- Using a reason that does not match the opinion is confusing because every reason should directly support the claim you made.
- Repeating the exact same sentence for the final opinion is less effective because the closing should restate the idea in fresh words.
Practice Questions
- 1 A student has 4 sentences: 1. Students should have more outdoor recess. 2. Fresh air helps students focus in class. 3. For example, many students return from recess calmer and ready to learn. 4. More outdoor recess would help students do their best work. Label each sentence as O, R, E, or O.
- 2 Write a 4-sentence OREO paragraph about whether homework should be limited to 30 minutes per night. Use exactly 1 sentence for each part: Opinion, Reason, Example, Opinion.
- 3 Read this draft: School should start later. Research shows tired students often score lower on tests. Teens need more sleep. Starting later would help students learn better. Explain which two middle parts are out of order and why the OREO structure works better.
