What this lesson covers
When you write to persuade or explain, you need to start with a claim—a statement you believe or want to convince others to accept. A claim is different from a fact (something known to be true), a question (something you're asking), or just a topic (a general subject). This lesson teaches you how to write a claim clearly, organize your reasons and evidence in a logical order, and make sure each reason has matching proof. These skills are the foundation of persuasive and explanatory writing.
What Is a Claim?
A claim is a statement that expresses your position, belief, or argument about a topic. It is something you want others to accept or agree with, but it is not automatically true just because you state it. That is why you need reasons and evidence to support it.
A claim is not a fact. A fact is something that is already known and proven: "The Earth orbits the sun" is a fact. A claim is an idea you are arguing for: "Students learn better when they have shorter lunch breaks" is a claim that needs reasons and evidence to support it.
A claim is not a question. A question asks something: "Should students have longer recess?" A claim answers it: "Students should have longer recess."
A claim is not just a topic. A topic is a subject area: "Sports" or "homework." A claim takes a stand on that topic: "Team sports teach leadership skills."
Your claim should be one clear sentence. It tells your reader exactly what you are arguing. When you state your claim plainly and early, your reader knows what to expect from the rest of your writing.

How to Write a Strong Claim
A strong claim is specific and arguable. It is not too broad, and it is not a statement everyone already agrees with.
Weak claim: "Video games are interesting." (Too vague; almost everyone finds something interesting.)
Strong claim: "Video games improve hand-eye coordination." (Specific and something people might disagree with.)
Weak claim: "Music is important." (Too broad; which kind of music? Important how?)
Strong claim: "Learning to play an instrument improves math skills." (Specific; arguable; clear what you will prove.)
When you write your claim, use clear, direct language. Do not hide your main idea in a long, complicated sentence. Avoid phrases like "I think" or "In my opinion" at the start—just state your claim. Your claim should stand on its own as a complete sentence. It is often a good idea to place your claim in the first or second sentence of your introduction, so your reader sees it right away and understands what your piece is about.

Organizing Reasons and Evidence
Once you have your claim, you need to decide what reasons support it and what evidence backs up each reason. A reason explains why your claim is true. Evidence is the proof—facts, examples, quotes, or data—that shows your reason is sound.
Each reason must have its own matching evidence. Do not list evidence without a reason, and do not list a reason without proof. When you organize, create a clear pairing:
| Claim | Our school should have a later start time | | Reason 1 | Teenagers need more sleep | | Evidence for Reason 1 | Studies show teens need 8–10 hours; early start means less sleep | | Reason 2 | Students are more alert in class with enough rest | | Evidence for Reason 2 | Teachers report better focus and fewer absences when students sleep more |
Choose an order that makes sense. You might organize from strongest reason to weakest, or from most familiar to least familiar. Some writers arrange reasons in the order they will develop them. The key is that your ordering is clear so your reader can follow your thinking.
Ask yourself: Does each reason connect to my claim? Is there evidence that proves this reason? Will my reader understand why I paired these two together? If you answer yes to all three, your organization is solid.

Keeping Claim, Reason, and Evidence Distinct
A common mistake is to blend your claim, reasons, and evidence together instead of keeping them separate and clear.
Blurred: "Our school should start later because teenagers need 8 to 10 hours of sleep and studies show they are more alert, so start times should change." (This sentence mixes claim, reason, and evidence without clear breaks.)
Clear: "Our school should start later." (Claim) "Teenagers need 8 to 10 hours of sleep to develop properly." (Reason) "Research by the American Academy of Pediatrics shows that early school start times reduce teen sleep and harm attention in class." (Evidence)
When you keep them distinct, your reader understands exactly what you believe, why you believe it, and what proof you have. Each part has a job. Your claim is the main argument. Your reason explains the logic. Your evidence is the supporting proof. Separating them in your outline or draft makes it easier to check that you have all three parts and that they match up correctly.
At this stage of your writing, you are not acknowledging opposing views or counterarguments. That skill comes later. Right now, focus on introducing your claim clearly and organizing your own reasons and evidence in a logical, paired structure.

Key terms
- Claim.
- A statement expressing your position or argument about a topic; it is something you believe or want others to accept, but it is not automatically true and requires reasons and evidence to support it.
- Fact.
- A statement that is already known and proven to be true, such as "Water freezes at 0 degrees Celsius"; facts do not need to be argued for.
- Reason.
- An explanation of why your claim is true; it answers the question "Why should someone believe your claim?"
- Evidence.
- Proof that supports a reason; it can be a fact, example, quote, statistic, or data that shows why your reason is sound.
- Topic.
- A general subject area you are writing about, such as "pets" or "exercise"; a topic is not the same as a claim.
- Arguable.
- A statement or idea that reasonable people can disagree about; a strong claim is arguable, not a universally accepted fact.
Worked example
Write a claim about a topic that matters to you. Then write two reasons that support your claim and at least one piece of evidence for each reason. You may choose your own topic or use one of these: Recess should be longer; Video games can teach valuable skills; Students should have less homework.
Let's choose the topic "Recess should be longer."
Step 1: Write your claim as one clear sentence.
Claim: "Students should have 30-minute recess periods instead of 20 minutes."
(This is specific and arguable. It is not just "Recess is fun" or "Recess is a topic.")
Step 2: Think of a reason that supports your claim.
Reason 1: "Longer recess gives students more time to exercise and stay physically healthy."
Step 3: Find evidence that proves this reason.
Evidence 1: "The American Heart Association recommends that children get 60 minutes of physical activity daily. Longer recess periods help students reach this goal during the school day."
Step 4: Repeat for your second reason.
Reason 2: "Students focus better in class when they have had time to play and rest their brains."
Evidence 2: "Teachers report that students are more attentive and complete more work in afternoon classes after a full recess break."
Step 5: Check your work.
Does each reason connect to the claim? Yes—both reasons explain why longer recess is good.
Does each reason have its own matching evidence? Yes—Reason 1 is matched with evidence about exercise, and Reason 2 is matched with evidence about classroom focus.
Are all three parts distinct and clear? Yes—the claim stands alone, each reason is separate, and each piece of evidence supports only its matching reason.
You are now ready to develop these into paragraphs in your full essay.

Practice questions
Which of the following is a claim rather than a fact, question, or topic?
- Is homework helpful?
- Homework
- Homework takes 30 minutes to complete.
- Homework helps students practice skills they learned in class.
Answer: Homework helps students practice skills they learned in class.
This is the only sentence that expresses an argument you could support with reasons and evidence. "Is homework helpful?" is a question. "Homework" is just a topic. "Homework takes 30 minutes to complete" is a fact. The correct answer makes a statement that reasonable people might debate—that is what makes it a claim.
Read the claim: "Wearing uniforms helps students focus on learning instead of clothing choices." Write a reason that supports this claim and one piece of evidence that proves your reason. Make sure your reason and evidence are distinct from each other.
Answer: Possible answer: Reason: "When all students dress the same, there is less distraction from what others are wearing." Evidence: "A study of three schools that adopted uniforms found that students reported fewer interruptions from thinking about fashion and more time spent on schoolwork."
A good reason explains why the claim is true. It should not repeat the claim word-for-word. The evidence must be different from the reason—it provides specific proof (a study, a statistic, an example, or a quote) that shows the reason is sound. If your reason and evidence say the same thing, you have not yet provided real proof. The reason and evidence should work together but stay separate.
You are planning an essay with this claim: "The school library should have extended hours after school." You have written two reasons and found evidence for both. Describe how you would organize these two pieces of information so your reader can follow your thinking.
Answer: Possible answer: I would organize from the strongest or most important reason first, followed by the second reason. For example, I would put the reason about helping students with homework first (because this might matter most to teachers and parents), then the reason about providing a safe space after school. I would make sure each reason is in its own paragraph with its matching evidence right after, so the reader sees clearly how the evidence supports each reason.
Good organization should make sense to your reader and be easy to follow. Common approaches include putting your strongest reason first, arranging reasons from most familiar to least familiar, or following the order you will use in your essay. What matters is that you can explain your choice and that your reasons and evidence are clearly paired so the reader understands how each piece of proof supports its matching reason.
FAQ
- Is a claim the same thing as an opinion?
- Not quite. A claim is more specific than an opinion. An opinion is a personal preference or belief, like "I like pizza." A claim is an argument you are willing to support with reasons and evidence, like "Pizza is the most popular food among teenagers." A claim may be based on your opinion, but it goes further by asking you to prove why it is true. In your writing, you are often expressing a claim, not just sharing an opinion.
- What if my evidence is just one example? Is that enough?
- One example can be a start, but it is usually stronger if you have multiple types of evidence—statistics, expert quotes, research, or several examples. One example might be a story someone told you, but does it prove your reason? Multiple examples or different types of proof (like a study plus an expert's statement) show your reader that your reason is solid, not just based on one person's experience.
- How do I know if my claim is too broad or too specific?
- A claim is too broad if it covers so much that you cannot support it well in the space you have. "Video games are bad" is very broad. A more specific claim, like "Violent video games can make teenagers less sensitive to real harm," gives you a clearer target to prove. A claim is too specific if it becomes a tiny detail rather than a real argument. "I played a video game on Tuesday" is too specific and not arguable. A good claim for a Grade 6 essay is one you can support with 2–3 solid reasons and evidence in 3–5 paragraphs.
- Should I use the words 'I think' or 'I believe' when I introduce my claim?
- No. State your claim directly without those phrases. Instead of "I think students should have later school start times," just write "Students should have later school start times." Your claim is clear and strong when you present it as a fact you are about to prove, not as something soft or uncertain.
