Claims & Reasons
Learn to write a one-sentence debatable claim, test it against fact, question, and bare topic, and back it with two or three distinct reasons that truly answer why.
What you'll do in this lesson
A voice-first session with the Crimsora tutor on Claims & Reasons, then targeted practice and FRQs — with the tutor adapting to where you get stuck.
What this lesson covers
Every argument you write starts with one sentence doing an enormous amount of work: the claim. A claim is not your topic, and it is not a fact anyone could look up. It is a position someone could reasonably disagree with — and that disagreement is exactly what makes the rest of your writing necessary.
In this lesson you will learn a quick three-part test that catches weak claims before you build a whole essay on top of them, and then you will learn how to generate two or three reasons that each answer the question why should anyone believe that? The hardest part is not finding reasons — it is noticing when your "second reason" is really your first reason wearing a different shirt, or when it has shrunk down into a single story that only proves one narrow thing. By the end, you will be able to draft a claim plus reasons frame in about five minutes and know it will hold weight.

What Counts as a Claim
A claim is a debatable position stated in one complete sentence. Three words in that definition matter.
Debatable means a thoughtful person, knowing the same information you know, could take the other side. If nobody could disagree, you have nothing to argue.
Position means the sentence takes a side. It does not describe a subject, announce what you plan to do, or ask what the reader thinks. Sentences that begin "In this essay I will explain..." or "There are many opinions about..." are not claims, because after reading them nobody knows where you stand.
One sentence is a discipline, not a decoration. If your claim needs three sentences, you probably have two claims tangled together, and your reasons will pull in two directions. Squeeze it down.
A useful habit: after writing your claim, imagine a classmate saying "I disagree." If that response makes sense, you have a claim. If the only sensible response is "okay, that's true" or "what about it?", revise. Students most often go wrong by writing something perfectly true and perfectly useless, such as "Sleep is important for teenagers." Nobody is going to fight you over that, so there is nothing to prove.

| Sentence | Claim? | Why |
|---|---|---|
| Middle school starts at 7:45 a.m. | No | Fact, checkable, nobody disagrees |
| Should school start later? | No | A question, takes no side |
| School start times | No | A bare topic, not a sentence |
| Middle schools should push their start time to 8:30 a.m. | Yes | Debatable position, one sentence |
The Three Tests: Fact, Question, Bare Topic
Before you invest an entire essay in a claim, run it through three fast checks. Each one catches a different way claims collapse.
The fact test. Ask: could I settle this with a search, a measurement, or a page in the textbook? If yes, it is information, not an argument. "The cafeteria serves lunch in twenty-five minutes" is verifiable. "Twenty-five minutes is too short for a lunch period" is arguable, because "too short" is a judgment someone could dispute.
The question test. Ask: is my sentence secretly a question, or does it merely repeat the prompt? Prompts often arrive as questions — "Should students be allowed to use phones during study hall?" A claim answers that question and commits. "Students should be allowed to use phones during study hall for academic work only" commits. "Whether phones should be allowed is a big debate" does not.
The bare topic test. Ask: is this just a subject with no verdict attached? "Homework," "year-round school," "uniforms" are topics. A topic tells the reader what you are thinking about; a claim tells them what you concluded.
One caution: adding "I think" does not turn a fact into a claim. "I think the cafeteria serves lunch in twenty-five minutes" is still just a fact, now stated less confidently. Strong claims sound direct. Drop "I believe," "I feel," and "in my opinion" — the sentence is yours already.

| Test | Question to ask | Fix if it fails |
|---|---|---|
| Fact | Could this be looked up and settled? | Add a judgment word: should, best, harms, worth |
| Question | Does my sentence take a side? | Answer the prompt in a declarative sentence |
| Bare topic | Is there a verdict, not just a subject? | Attach a predicate that argues something |
Reasons That Actually Answer Why
A reason is a statement that answers the question "why should I believe this claim?" The fastest way to test one is the because test: say your claim, add the word because, and attach the reason. If the sentence makes sense and feels like it moves the argument forward, you have a real reason.
Claim: Middle schools should push their start time to 8:30 a.m. ... because teenagers' natural sleep cycles make early mornings biologically harmful. That works. It supplies a cause the reader did not already have.
Now watch a failure: ... because starting later would be better for students. That is the claim again, reworded. Nothing new entered the sentence. This is the most common problem in Grade 7 argument drafts — the writer produces three reasons that are all the original claim in different vocabulary.
Strong reasons are also distinct from each other. Two reasons are distinct when knocking one down leaves the other standing. "Students would be more rested" and "students would get more sleep" are the same reason twice. "Students would be more alert in first period" and "later start times reduce teen car accidents on the morning commute" are genuinely separate — one is about learning, one is about safety.
Aim for two or three reasons, not five. Three well-developed reasons beat five thin ones, because each reason will eventually need its own paragraph of support.
A quick way to generate distinct reasons is to look at your claim from different angles: health, money, fairness, safety, learning, time. Ask what your claim does for each angle. Angles that produce nothing get dropped; angles that produce something usually produce something different from the others.

Two Traps: Restating and Shrinking
Two specific failures show up over and over, and both are easy to catch once you know their shape.
Restating is when a reason recycles the claim. It usually hides behind synonyms or an adverb. Claim: "Schools should require a daily recess for seventh graders." Restated reason: "because seventh graders need recess every day." Read it aloud and you can hear the loop. The cure is to ask what the reason would look like as a cause: what does recess do? It resets attention, it gives students who struggle socially unstructured time to make friends, it is the only physical activity some students get all day. Those are causes. The claim was an effect.
Shrinking is when a reason collapses into one example. "Because last Tuesday Marcus fell asleep in math" is not a reason; it is a single incident. It can support a reason, but it cannot be one, because a reader can dismiss it with "that is one kid, one day." A reason states something general enough to cover many cases; the example lives underneath it. Keep the general statement as your reason and save Marcus for your body paragraph.
When you are unsure, ask a classmate to respond to each reason with "so what?" A restated reason has no answer. A real reason does.

| Draft | Problem | Repaired reason |
|---|---|---|
| ...because later starts are better | Restates the claim | ...because alertness in first period rises when sleep matches teen biology |
| ...because my brother missed the bus once | Shrunk to one example | ...because rushed mornings increase tardiness across the whole grade |
| ...because students want it | Restates preference, adds no cause | ...because students who choose their own schedules report finishing homework earlier |
Putting the Frame Together
Once your claim survives the three tests and your reasons survive the because test, write them as a single planning frame before drafting anything else. The frame is short on purpose.
Claim: one sentence, debatable, no hedging. Reason 1: because ... Reason 2: because ... Reason 3 (optional): because ...
Check the frame three ways. First, coverage: do the reasons together actually make the claim believable, or do they all cover the same corner of it? Second, independence: cross out reason 1 and see whether reason 2 still stands on its own. Third, order: reasons are not interchangeable in a finished essay, so note which one a skeptical reader would find hardest to dismiss.
This frame is the skeleton the rest of the unit hangs on. Each reason will later need its own support and explanation, and your argument will eventually need to face the strongest objection someone could raise. None of that works if the skeleton is crooked. A reason that quietly restates the claim will produce a body paragraph with nothing to say, and writers usually discover that halfway through drafting, when it is expensive to fix.
One last habit worth building: write the claim last-ish. Many writers brainstorm reasons first, notice which ones are strongest, and then sharpen the claim so it matches. If your best reasons all point toward "phones should be allowed for academic work only," do not stubbornly argue "phones should be allowed always." Let the evidence steer the position. Adjusting a claim to fit strong reasoning is a sign of good thinking, not indecision.

Key terms
- Claim.
- A debatable position stated in one complete sentence; the main thing an argument sets out to prove.
- Debatable.
- Describes a statement a reasonable, informed person could disagree with. If no disagreement is possible, the statement is a fact, not a claim.
- Reason.
- A general statement that answers why the claim is true. Tested by placing it after the claim plus the word because.
- Bare topic.
- A subject with no verdict attached, such as "school uniforms." A topic names what you are thinking about; a claim states what you concluded.
- Restating.
- A weak reason that repeats the claim in different words instead of supplying a cause, so it adds nothing new to the argument.
- Shrinking.
- A weak reason that collapses into one specific incident. Single examples belong under a reason as support, not in place of one.
- Distinct reasons.
- Reasons that stand independently, so that disproving one leaves the others intact. Usually they come from different angles such as safety, cost, fairness, or learning.
- Because test.
- A quick check in which you say the claim, add because, and attach the reason. If the result sounds circular or empty, the reason needs work.
Worked example
Your teacher gives this prompt: "Should your school replace its letter grades with written feedback?" Draft a claim and two or three distinct reasons, showing your testing along the way.
Step 1 — Reject the non-claims. "Grading systems" is a bare topic. "Should grades be replaced?" is the prompt repeated as a question. "Our school currently uses letter grades on a 100-point scale" is a fact anyone could confirm in the handbook. None of these takes a side.
Step 2 — Draft a position. Try: "Our school should replace letter grades with written feedback." Run the tests. Fact test: no search settles "should," so it passes. Question test: it answers the prompt and commits. Bare topic test: there is a verdict, not just a subject. It is one sentence, with no "I believe" attached. This is a workable claim.
Step 3 — Brainstorm reasons by angle. Learning: written comments tell a student what to do next; a letter does not. Fairness: letter grades compress very different performances into the same symbol. Stress: chasing a letter pushes students toward safe work instead of hard work. Cost: written feedback takes teacher time — that angle actually argues against the claim, so set it aside for later in the unit.
Step 4 — Apply the because test. "Our school should replace letter grades with written feedback because a letter tells a student where they landed but not what to change." Good — that supplies a cause. Compare a bad one: "...because written feedback is better than letter grades." That is the claim again. Cut it.
Step 5 — Check independence. Reason 1 is about improvement. Reason 2, "because students chasing a letter avoid challenging work they might not master immediately," is about risk-taking. Knock down either one and the other survives. They are distinct.
Step 6 — Final frame. Claim: Our school should replace letter grades with written feedback. Reason 1: because a letter reports where a student landed but never says what to change next. Reason 2: because students protecting a letter choose safe assignments over challenging ones. Reason 3: because a single letter hides large differences between two students who received the same mark for very different work.
Notice that no single classroom story appears in the frame. Those stories are support, and they belong in the paragraphs that follow.

Practice questions
Which sentence is the strongest claim for an argument about school lunch periods?
- Lunch periods at our school last twenty-five minutes.
- Should students have a longer lunch period?
- Our school should extend lunch to forty minutes because rushed eating harms digestion and cuts out the only unstructured social time in the day.
- School lunch periods
Answer: Our school should extend lunch to forty minutes because rushed eating harms digestion and cuts out the only unstructured social time in the day.
The first option is a fact that can be checked in the schedule, so nobody can argue with it. The second is a question — it takes no side. The fourth is a bare topic with no verdict at all. The third states a debatable position in one sentence and even previews two distinct reasons, one about health and one about social time. Some students hesitate over the third because it feels long, but length is not the test; taking an arguable side in a single sentence is.
Look at this draft. Claim: "Seventh graders should be allowed to choose their own novels for independent reading." Reason 1: "because students should get to pick what they read." Reason 2: "because last month Jenna read four books after she found a mystery series she liked." Explain what is wrong with each reason and rewrite both.
Answer: Reason 1 restates the claim; Reason 2 shrinks into a single example. Rewrites might be: "because students who select their own books read more pages outside of class" and "because choosing a book teaches students to judge difficulty and interest for themselves, a skill assigned reading never practices."
Reason 1 swaps "be allowed to choose" for "get to pick" — a synonym, not a cause. Run the because test and you hear the loop: the sentence never explains why choice helps. Reason 2 names one student and one month. A reader can dismiss it instantly with "that is one person." Jenna is not useless, though — she becomes strong support inside the paragraph for a general reason about volume of reading. The repaired reasons are also distinct from each other: one is about how much students read, the other about a skill they build, so disproving one leaves the other standing.
A classmate writes the claim "Recycling is important for the environment." Using the three tests, explain whether this works as a claim and revise it if it does not.
Answer: It fails the debatable requirement. Almost nobody would argue the opposite, so there is nothing to prove. A revision such as "Our school should require sorted recycling bins in every classroom rather than relying on a single bin in the cafeteria" gives a specific, arguable position.
The sentence passes the question test and the bare topic test — it is a declarative sentence with a predicate. But it fails on debatability, which is the heart of the fact test. Imagine a classmate replying "I disagree, recycling is unimportant." Practically no one would say that, so the essay has no work to do. The fix is to narrow toward a specific action or judgment someone could genuinely oppose: a requirement, a cost, a change in policy. Notice the revision also invites reasons immediately, such as convenience, contamination rates, and student habits.
FAQ
- How long should my claim be?
- One sentence. It can be a fairly long sentence, and it may include a preview of your reasons, but if you need two or three sentences to state your position, you probably have two positions tangled together. Split them, pick the one your reasons actually support, and drop the other.
- Is it okay to write "I think" or "in my opinion" in a claim?
- Skip them. The reader already knows the essay is your thinking, so those phrases only make the sentence sound less certain. They also do not fix a weak claim: "I think the bus arrives at 7:10" is still a fact, just hedged. Write the position directly and let your reasons carry the confidence.
- What is the difference between a reason and evidence?
- A reason is a general statement answering why your claim is true. Evidence is the specific material — data, quotations, examples, expert statements — that shows the reason is trustworthy. Reasons form the skeleton of your argument; evidence goes underneath each one. Your next lesson focuses on gathering and explaining that evidence.
- How many reasons do I need?
- Two or three. Three well-developed reasons almost always beat five thin ones, because each reason will get its own paragraph of support and explanation. Before you settle, cross out one reason and see whether the rest still hold — if two reasons are really the same reason worded twice, you have fewer than you think.
