Why Do We Argue in Writing?
Humans have been making arguments for thousands of years. Long before anyone typed an essay on a computer, people tried to convince others by organizing their thoughts clearly. Let's look at how the skill of persuasive writing (writing that tries to change someone's mind) grew over time.
Every time you write a persuasive essay, a book review, or even a convincing text to a friend, you're doing what great thinkers have done for centuries. The big question this lesson answers is: How do you state a claim and arrange your reasons and evidence so they make sense to your reader?
Core Principles: The Building Blocks of an Argument
Before you can organize an argument, you need to know its parts. Think of an argument like building a house. You need a foundation (your claim), walls (your reasons), and bricks (your evidence). Here are the four key building blocks.
Claim
Reasons
Evidence
Organization
Visual Map: How an Argument Fits Together
The diagram below shows how a well-organized argument flows from top to bottom. Notice how the claim sits at the very top, each reason branches out below it, and every reason is supported by its own evidence. At the bottom, the conclusion ties everything together.
This tree shape is the backbone of every strong argument essay. Your claim is stated first so the reader knows your position right away. Then each reason gets its own paragraph, filled with evidence that proves that reason is true. Finally, the conclusion restates the claim and reminds the reader why all the evidence matters.
How It Works: Writing Step by Step
Now that you know the parts, let's walk through the process of actually writing an organized argument. There are four main steps, and each one builds on the last.
Step 1 — Pick a Clear Claim
Your claim should be debatable, meaning not everyone would automatically agree with it. "Pizza is a food" is a fact, not a claim. But "Pizza should be served in the school cafeteria every day" is a claim because someone could disagree. A strong claim also tells the reader exactly what you'll argue — no vague words like "stuff" or "things."
Step 2 — Choose 2–3 Strong Reasons
Each reason should answer the question "Why?" If your claim is that pizza should be served daily, one reason might be: "Pizza provides important nutrients that growing students need." Keep each reason different from the others so you aren't repeating yourself.
Step 3 — Gather Evidence for Each Reason
Evidence is where you prove your reasons. You might use a fact ("Tomato sauce is rich in vitamin C"), a statistic ("78% of students in a school survey said they eat more when pizza is on the menu"), or an expert quote ("Dr. Smith, a nutritionist, says cheese provides calcium for strong bones"). Match each piece of evidence to the reason it supports.
Step 4 — Organize Everything in a Logical Order
The most common structure is called "strongest-to-weakest" or "weakest-to-strongest." Many writers save their best reason for last so the reader finishes feeling convinced. You can also use order of importance or group reasons by topic. The key is that your reader should never feel lost.
Types of Evidence You Can Use
Not all evidence is the same. Some types are stronger than others, and knowing the difference helps you pick the best proof for each reason. Here's a handy guide.
| Type of Evidence | What It Is | Example | Strength |
|---|---|---|---|
| Fact | Something that can be proven true | "The Earth orbits the Sun." | Very strong — hard to argue against |
| Statistic | A number from research or a survey | "9 out of 10 dentists recommend brushing twice a day." | Strong — numbers feel convincing |
| Expert Quote | Words from someone who really knows the topic | "According to Dr. Lee, reading for 20 minutes a day improves vocabulary." | Strong — borrows the expert's knowledge |
| Example | A specific real-life case or story | "At Lincoln Middle School, adding recess increased test scores." | Medium — one example doesn't prove a rule, but it helps |
| Personal Experience | Something that happened to you | "When I joined the debate club, I became more confident speaking." | Weaker alone — stronger when combined with other evidence |
A smart writer mixes different types of evidence. If you only use personal experience, your argument may feel weak. But if you pair that personal experience with a fact and an expert quote, your argument becomes much more convincing. Try to include at least two types of evidence for each reason in your essay.
Worked Example: Building an Argument from Scratch
Let's say your teacher asks you to write a short argument about this topic: "Should students be allowed to use phones during lunch?" Watch how we build the argument step by step.
Strengths & Common Pitfalls
Even great writers make mistakes when organizing arguments. Let's compare strong writing moves with pitfalls you'll want to avoid.
| What to Do ✅ | What to Avoid ❌ | Why It Matters |
|---|---|---|
| State your claim in the first paragraph. | Burying your claim in the middle of the essay. | Your reader should know your position right away. |
| Give each reason its own paragraph. | Mixing two or three reasons into one messy paragraph. | Separate paragraphs keep ideas clear and easy to follow. |
| Use evidence that matches each reason. | Dropping in random facts that don't connect to your point. | Mismatched evidence confuses the reader. |
| Use transition words ("First," "In addition," "Finally"). | Jumping from idea to idea without signals. | Transitions act like road signs — they guide the reader. |
| Restate the claim in the conclusion. | Ending suddenly or introducing a brand-new idea. | A conclusion gives your reader a sense of closure. |
Beyond 6th Grade: Where This Skill Goes Next
The skills you're learning now are the foundation for more advanced argument writing in later grades. Here's a quick look at how things build as you grow as a writer.
| Skill Level | What You Do Now (6th Grade) | What Comes Next (7th–8th Grade & Beyond) |
|---|---|---|
| Claim | State a clear opinion with a preview of your reasons. | Craft a thesis statement that also acknowledges the opposing side. |
| Reasons | Provide 2–3 separate reasons, one per paragraph. | Develop sub-claims that build on each other logically. |
| Evidence | Use facts, statistics, and examples. | Cite sources formally (MLA or APA format) and evaluate how reliable they are. |
| Counterarguments | You're just starting to learn about them. | Address the counterargument directly and explain why your claim is still stronger. |
| Organization | Intro → Body paragraphs → Conclusion. | Use advanced structures like compare-and-contrast or problem-solution within your argument. |
Don't worry about mastering all of that right now. The important thing is that every skill you practice today — writing a strong claim, choosing good evidence, organizing clearly — is a skill you'll use for the rest of your life, whether you're writing a college essay, a job application, or even a convincing email to your boss.

Lesson Summary
In this lesson, you learned that a strong argument begins with a claim — a clear, debatable statement that tells your reader exactly what you believe. Each claim is supported by reasons, which answer the question "Why do you think that?" Every reason needs evidence — facts, statistics, expert quotes, or examples — to prove it is true. The way you arrange all of these pieces is called organization, and the best essays use one reason per paragraph, transition words to guide the reader, and a conclusion that restates the claim. You also explored different types of evidence and learned that stronger evidence (like facts and expert quotes) makes your argument more convincing than weaker evidence (like personal experience) alone.
Remember: writing a great argument is a skill that improves with practice. Every time you state a claim, back it up with solid reasons and evidence, and organize your ideas clearly, you become a stronger, more persuasive writer. These same skills will help you in 7th and 8th grade, in high school, and well beyond — any time you need to make your case and convince someone that your ideas matter.
