Teaching Opinion Writing in Elementary

Teaching Resources › Writing Teaching Guides › Teaching Opinion Writing

“Pizza is the best food” is an opinion. So is “Our school should have longer recess.” Most students can state an opinion the moment you ask for one — what they can’t do, without instruction, is defend it. Ask a third grader why recess should be longer and you’ll often get “because it just should” or “because recess is fun.” The whole job of opinion writing is teaching students to move from having an opinion to supporting one with reasons a reader will take seriously. This guide covers how to teach opinion writing in grades 3–6 and pairs with the printable opinion writing prompts and activities for classroom practice.

Opinion writing is the first form of argument students meet, and it is on every state ELA standard from grade 1 onward (it becomes “argument” writing in the upper grades). It is also the genre where the gap between a strong and a weak paper is widest — and most fixable. The moves are concrete: state a clear opinion, back it with reasons, support each reason with evidence, and close by restating the position. Teach that frame and students stop writing “because it just is.”

Opinion vs. Fact: The Boundary Students Have to See First

Before a student can write a good opinion piece, they have to know what an opinion is — and isn’t. The most common early error is writing a string of facts and calling it an opinion, or stating an opinion and treating it as a proven fact. Make the boundary explicit:

• Fact: a statement that can be checked and proven true or false. The school day is six hours long.
• Opinion: a statement of belief, preference, or judgment that people can reasonably disagree about. The school day is too long.

The skill of sorting fact from opinion is its own reading lesson, and it pays off directly here — students who can spot the difference write cleaner claims and stronger support. If your class needs that groundwork first, the reading guide on teaching fact and opinion sets it up. The key idea to carry into writing: a good opinion piece is built on an opinion (the claim) but supported with facts (the evidence). It needs both.

The Shape of an Opinion Piece: State, Reasons, Evidence, Restate

Students write far better opinion pieces when they have a structure to fill rather than a blank page to fear. The classic elementary frame — sometimes taught as “OREO” (Opinion, Reasons, Evidence, Opinion restated) — gives them that shape. Four parts, in order:

1. State your opinion. One clear sentence that tells the reader exactly what you think. Our class should have a pet hamster.
2. Give your reasons. Two or three reasons that answer the question “why?” Each reason is a separate point, not a restatement of the opinion.
3. Support each reason with evidence. A fact, an example, or an explanation that makes the reason convincing. This is the part students skip, and the part that separates a real argument from a wish.
4. Restate your opinion. A closing sentence that returns to the position, now that the reader has heard the case for it.

Drawing the four parts as a stack on the board — and color-coding a sample piece so students can see where the opinion, reasons, and evidence each live — makes the structure click. This is exactly how the opinion writing lessons build the skill: state a position, then reasons, then the evidence that holds each reason up.

Reasons vs. Evidence: The Distinction That Does the Work

If you teach one thing about opinion writing explicitly, make it the difference between a reason and the evidence that backs it. Students collapse the two constantly — they give a reason, then restate the same reason in slightly different words, and think they’ve supported it.

• Opinion: Our class should have a pet hamster.
• Reason: A class pet teaches responsibility.
• Evidence (supports the reason): Students would sign up for a feeding-and-cleaning schedule, so each person would be in charge of the hamster for a week and learn to take care of a living thing.

The test to teach students: after every reason, ask “how do I know? what’s my proof?” If the next sentence just says the reason again, it’s not evidence yet. Evidence is the example, fact, or explanation that a doubtful reader would need. A reason tells the reader what to think; evidence shows them why they should.

Sentence Stems That Get Students Started

Opinion writing has a small set of signal phrases that do a lot of work, and giving students the stems removes the “I don’t know how to start” barrier. Post them and let students lean on them until the moves are automatic:

• Stating the opinion: I believe… / In my opinion… / Our school should…
• Giving reasons: One reason is… / Another reason is… / Most importantly…
• Adding evidence: For example… / This is shown by… / According to…
• Restating the opinion: For these reasons… / This is why I think… / As you can see…

The reason and evidence stems double as transitions — they signal to the reader that a new point is coming or that support is arriving. For the broader set of connecting words that hold an argument together, the guide on transitional words and phrases covers the ones opinion writers rely on most.

Where Students Get Stuck (and How to Help)

Four problems account for nearly every weak opinion draft. Naming each one for students — and giving it a fix — does far more than “add more detail” feedback.

1. The opinion is missing or buried

The draft launches into reasons without ever stating, in one clean sentence, what the writer actually thinks. Fix: require an opinion sentence as line one, using a stem. If a reader can’t underline the opinion in the first sentence, it isn’t clear enough yet.

2. Reasons with no evidence

The piece lists reasons — it’s fun, it’s good, everyone wants it — but never supports any of them. Fix: the “how do I know?” question after every reason. One well-supported reason beats three bare ones.

3. “Because it just is”

The reason restates the opinion instead of explaining it. Recess should be longer because recess should be longer. Fix: push for the why behind the why — longer recess helps students focus better afterward, gives them exercise they need, reduces conflicts that come from being cooped up. Each of those is a real, supportable reason.

4. No counterargument (upper grades)

By grades 5–6, a strong opinion piece acknowledges the other side — some people think a class pet is too much work, but… — and answers it. Fix: teach the “some people think… but…” move once the basic four-part structure is solid. Addressing an objection makes the writer look fair and the argument look stronger.

A Suggested One-Week Mini-Unit

Opinion writing rewards a build-the-parts sequence that ends in one polished piece, rather than a single “write your opinion” assignment. A workable one-week shape:

• Day 1 — Fact vs. opinion + a clear claim. Sort facts from opinions; practice writing one-sentence opinion statements with stems.
• Day 2 — Reasons. For a shared class opinion, brainstorm reasons; sort the strong reasons from the weak (“it’s fun”) ones.
• Day 3 — Evidence. The “how do I know?” move; match evidence to each reason.
• Day 4 — Drafting. Write the full piece from an OREO plan: opinion, reasons, evidence, restated opinion.
• Day 5 — Revise and share. Strengthen the weakest reason, sharpen the opening and closing, read finished pieces aloud.

The drafting and revision days pair naturally with the broader guide on paragraph writing — a well-structured opinion piece is, at its core, a paragraph (or a few) with a clear topic sentence and supporting details.

Where Opinion Writing Goes Next

The opinion-writing skills students build in elementary school are the foundation for nearly all the persuasive and analytical writing that follows.

• Argument and persuasive essays. The state-reasons-evidence frame is the same backbone of the multi-paragraph argument essays of middle and high school — just with stronger evidence and a required counterargument.
• Persuasive writing across genres. Letters to the editor, book and movie reviews, and proposals all run on the same claim-and-support engine.
• Reading comprehension. Students who write arguments read them more critically — they can spot an author’s claim, weigh the evidence, and notice when support is missing.
• Standardized writing tests. Opinion/argument is one of the three core text types assessed on most state ELA exams, alongside narrative and informative writing.
