Why Conclusions Matter: A Brief History
People have been trying to persuade each other for thousands of years. From ancient Greek speeches to modern blog posts, writers and speakers have always known that how you end matters just as much as how you begin. A strong conclusion is the last thing your reader sees—and it shapes what they remember most.
Here's the big question this lesson answers: How do you write a conclusion that doesn't just repeat what you said, but actually makes your argument stronger? That's what we're going to figure out together.
Core Principles of a Strong Conclusion
A concluding statement (or concluding section) is the final part of your argumentative essay. It wraps up your writing by reminding the reader of your main claim and leaving them with something to think about. There are four key principles that make a conclusion work well.
Restate, Don't Just Repeat
Follow From Your Evidence
Support the Argument
End With Impact
The Anatomy of an Argument (Visual Guide)
Let's look at how an argumentative essay is built from top to bottom—and where the conclusion fits in. Notice how the conclusion connects to every part above it, not just the introduction.
See those dashed green arrows? They show that your conclusion follows from every part of the essay. It pulls ideas from the introduction (your claim), the body paragraphs (your evidence and reasons), and then supports the argument by tying them all together in one final statement. If your conclusion mentions something that isn't in the body paragraphs, those arrows would be broken—and so would your essay's logic.
How to Build a Conclusion: The Step-by-Step Process
Writing a strong conclusion isn't about having magical writing talent. It's a process you can learn and practice. Here's a simple method you can use every time you write an argumentative essay.
Let's break down each piece of this formula so you know exactly what to write.
Step 1 — Restate Your Claim (in New Words)
Go back and read your thesis statement (the sentence that tells your reader what you believe). Now rewrite that idea using different words. Don't copy it exactly—rephrase it. This reminds your reader of the main point without sounding robotic.
Step 2 — Briefly Touch on Your Key Reasons
Look at the main reasons from your body paragraphs. Mention them briefly (you don't need to give all the details again). This shows the reader that your conclusion connects to everything you already proved. This is the "follows from" part.
Step 3 — End With a Final Thought
This is where you leave your reader with something memorable. You have several options here. You could ask a question that makes the reader keep thinking. You could suggest what should happen next (a call to action). You could explain why the topic matters in a bigger way. Or you could end with a short, powerful statement that drives your point home.
Notice how each step builds on the one before it. You start by reminding the reader of your claim, then you connect it to your evidence, and finally you leave them with something that makes your argument feel complete. That's the "follows from and supports" standard in action.
Strong vs. Weak Conclusions: A Detailed Breakdown
One of the best ways to understand what makes a conclusion work is to compare examples. Let's look at what strong conclusions do right—and what weak conclusions get wrong.
| Feature | Weak Conclusion ❌ | Strong Conclusion ✅ |
|---|---|---|
| Claim | Copies the thesis word-for-word | Rephrases the claim in fresh language |
| Connection to body | Doesn't mention any reasons or evidence | Briefly references key reasons from body paragraphs |
| New information | Introduces a brand-new argument | Stays connected to what was already discussed |
| Final sentence | Ends abruptly or says "That's why I think…" | Ends with a call to action, question, or big-picture statement |
| Phrases to avoid | "In conclusion," "As I said before," "That is all" | Uses varied, confident transitions |
| Overall effect | Feels rushed, disconnected, or boring | Feels satisfying, logical, and memorable |
Let's see this in action with a real example. Imagine you wrote an essay arguing that schools should start later in the morning.
❌ Weak Conclusion
See the problems? It just repeats the thesis, doesn't mention any of the evidence from the body paragraphs, and ends with a vague statement that doesn't leave an impression.
✅ Strong Conclusion
This version restates the claim in a new way, references two key reasons from the body paragraphs (test scores and car accidents), and ends with a call to action directed at school boards. That's a conclusion that follows from and supports the argument.

Common Strengths and Pitfalls
Now that you know the process, let's talk about the most common mistakes students make—and the habits that strong writers have. Knowing what to avoid is just as important as knowing what to do.
| ✅ DO THIS | ❌ AVOID THIS | WHY IT MATTERS |
|---|---|---|
| Rephrase your claim in fresh words | Copy-paste your thesis exactly | Readers can tell when you're being lazy, and it breaks the flow |
| Reference your body paragraph reasons | Introduce brand-new evidence or arguments | New info belongs in the body; it confuses readers in the conclusion |
| End with a call to action or big idea | End with "In conclusion" or "That's all" | Overused phrases sound weak and tell the reader nothing new |
| Keep it 3–6 sentences | Write one sentence or an entire new paragraph of evidence | Too short = rushed; too long = you're writing another body paragraph |
| Use confident, definitive language | Say "I think maybe" or "It could possibly be" | Your conclusion should sound sure—you've already proved your point! |
Beyond 7th Grade: Where This Skill Takes You
Writing a strong conclusion isn't just a 7th grade skill—it's something you'll use all the way through high school, college, and even in your career. Here's how this idea grows as you grow.
| Level | What Your Conclusion Does | What's New |
|---|---|---|
| 7th Grade (You!) | Restates claim, references key reasons, ends with a final thought | Learning the foundational structure |
| 8th–9th Grade | Everything above + addresses counterarguments in the conclusion | Showing you understand the other side |
| 10th–11th Grade | Everything above + connects to broader themes or historical context | Thinking about "so what?" on a bigger scale |
| College & Beyond | Everything above + suggests areas for future research or deeper questions | Contributing to ongoing conversations |
The core idea stays the same at every level: your conclusion must follow logically from your argument and make it stronger. Right now you're building the foundation, and every essay you write from here on will use this skill. The better you get at conclusions now, the easier persuasive writing will be in the future.

Lesson Summary
A concluding statement is the final section of your argumentative essay, and its job is to wrap up your argument in a way that feels complete and convincing. To write one that "follows from and supports the argument presented," you need to do three things. First, restate your claim using different words than your original thesis. Second, briefly reference the key reasons from your body paragraphs so the reader can see how everything connects. Third, end with a final thought that leaves an impression—a call to action, a thought-provoking question, or a statement about why your topic matters in the big picture.
Remember: a strong conclusion never introduces brand-new evidence, never copies the thesis word-for-word, and never feels rushed. It should feel like the last powerful note in a song—the one that makes everything before it sound better. Use the three-step formula (Restated Claim + Key Reasons Summary + Final Thought) every time you write, and your conclusions will be clear, connected, and impossible to forget.
