SECTION 1
Why Conclusions Matter: A Brief History
People have been writing arguments for thousands of years. From ancient Greek philosophers to modern newspaper writers, every strong argument needs a strong ending. A concluding statement (the final sentences or paragraph that wraps up your argument) is like the final buzzer in a basketball game — it signals that you're done and reminds everyone of the score.
~400 BCE • Aristotle's Rhetoric
1700s • Persuasive Pamphlets
1900s • The Five-Paragraph Essay
2010 • Common Core Standards
Throughout history, the best writers have known one thing: if your ending is weak, your whole argument feels weak. So how do you write a conclusion that leaves your reader convinced? That's exactly what this lesson will teach you.
SECTION 2
Core Principles of a Strong Conclusion
A conclusion is not just repeating everything you already said. It has a specific job: to tie your argument together and leave the reader with a clear understanding of your position. Let's look at the key principles that make a conclusion work.

Visualizing the Argument Essay Structure
Before we dig deeper into conclusions, it helps to see where the conclusion fits within the bigger picture of an argument essay (an essay where you pick a side and try to convince the reader). The diagram below shows the whole structure, with the conclusion highlighted at the bottom.
As you can see, the conclusion doesn't come out of nowhere. It "follows from" everything above it. The word "follows" is important in the Common Core standard — it means your ending should feel like it naturally grows out of the argument you already made.
SECTION 4
How a Conclusion Works: The Three-Part Formula
Writing a conclusion can feel tricky, but there's a formula you can follow. Think of it as three building blocks that stack on top of each other. Let's break each one down.
Part 1: Restate the Claim
Your claim (your main argument or opinion) was stated in your introduction. Now you need to say it again, but in a fresh way. If your original claim was "Schools should serve healthier lunches," your conclusion might say "It's clear that healthier lunch options would benefit every student." Same idea, different words.
Part 2: Sum Up Your Reasons
You don't need to repeat every detail from your body paragraphs. Just quickly remind the reader of your strongest points. Think of this like a movie trailer — you're showing the highlights, not the whole film. One or two sentences is usually enough.
Part 3: Leave a Lasting Impression
This is your chance to make your reader feel something or think about your topic after they stop reading. You have several tools for this. You can use a call to action (tell the reader what to do), a thought-provoking question, or a big-picture connection that shows why your topic matters beyond your essay.

Conclusion Strategies: Choosing the Right Ending
Not all conclusions look the same. There are different strategies you can use for that final lasting impression. The diagram below shows four popular strategies, along with examples of what they look like in practice.
You can mix and match these strategies. For example, you could circle back to your introduction and add a call to action. The key is to choose a strategy that fits your topic and makes your reader feel like your argument is complete.
SECTION 6
Worked Example: Writing a Conclusion Step by Step
Let's walk through writing a conclusion for a real argument essay. Imagine you wrote an essay arguing that students should have longer recess. Your claim was: "Elementary schools should extend recess to at least 30 minutes every day." Your body paragraphs covered two reasons: (1) longer recess improves focus in class, and (2) it helps students stay physically healthy.
Writing a Conclusion for "Longer Recess"
- 1
Step 1 — Restate the Claim in New Words
Don't copy your thesis word for word. Find a fresh way to say the same idea. Original claim: "Elementary schools should extend recess to at least 30 minutes every day." Restated: "Giving students more time for recess is one of the smartest changes a school can make.""Giving students more time for recess is one of the smartest changes a school can make." - 2
Step 2 — Briefly Summarize Your Reasons
Touch on your two main reasons in one or two sentences. Keep it short — just the highlights. "Research shows that longer breaks help kids focus better in class. On top of that, active play keeps students healthier and more energetic throughout the day."Two sentences summarizing the two body paragraphs. - 3
Step 3 — Choose a Strategy for Your Lasting Impression
Let's use the "call to action" strategy. We want to tell the reader to do something. "If you believe students deserve to do their best, talk to your school board about making recess longer — every kid deserves that chance."A call to action that connects directly to the claim. - 4
Step 4 — Put It All Together
Now combine all three parts into one smooth paragraph. Here is the final conclusion:"Giving students more time for recess is one of the smartest changes a school can make. Research shows that longer breaks help kids focus better in class. On top of that, active play keeps students healthier and more energetic throughout the day. If you believe students deserve to do their best, talk to your school board about making recess longer — every kid deserves that chance."

Dos and Don'ts of Concluding Statements
Now that you know what to include in a conclusion, let's look at common mistakes students make — and what you should do instead. The table below compares strong conclusion moves with weak ones.
| ✅ DO This | ❌ DON'T Do This |
|---|---|
| Restate your claim using different words. | Copy and paste your thesis from the introduction. |
| Briefly mention your key reasons. | Retell every single detail from the body paragraphs. |
| End with a call to action, question, or big-picture connection. | End with "And that is why I think…" and stop. |
| Keep your conclusion connected to your argument. | Bring up a brand-new argument or evidence. |
| Use a confident, strong tone. | Use weak phrases like "I guess" or "I might be wrong." |

Beyond 6th Grade: How Conclusions Grow Up
The skills you're learning now will keep growing with you. As you move through middle school and into high school, conclusions get longer and more complex. Here's a peek at how conclusions change as you advance.
| Feature | 6th Grade (You Are Here!) | 8th Grade & Beyond |
|---|---|---|
| Length | 3–5 sentences in one paragraph | A full paragraph or even a concluding section with multiple paragraphs |
| Claim Restatement | Restate your claim in different words | Restate your claim and show how your argument proved it |
| Counterargument | Not usually addressed in the conclusion | May acknowledge the other side one more time and explain why your argument is still stronger |
| Lasting Impression | A question, call to action, or connection | Deeper analysis of implications, connections to larger social or ethical issues |
How conclusions grow more complex as you advance in school
Don't worry about getting to that advanced level right now. If you can master the three-part formula — restate your claim, summarize your reasons, and leave a lasting impression — you'll have a strong foundation for every argument essay you write in the future.

SUMMARY
Summary: Wrapping Up Your Argument with Confidence
Summary
A strong concluding statement for an argument essay has three key parts. First, you restate your claim using different words than your introduction. Second, you briefly summarize your key reasons — just the highlights, not every detail. Third, you end with a lasting impression that makes the reader keep thinking. You can do this with a call to action, a thought-provoking question, a big-picture connection, or by circling back to your opening hook.
Remember: your conclusion must follow logically from your argument. That means no new evidence, no new arguments, and no sudden changes in direction. Think of it as tying a neat bow around the gift of your essay. When you master this skill, every argument you write will feel complete, convincing, and worth remembering.
