Why Conclusions Matter: A Brief History
Imagine watching a movie that just stops in the middle. No ending. No resolution. You'd feel confused and frustrated, right? That's exactly how a reader feels when an argument essay has no conclusion. Writers have understood the power of strong endings for thousands of years.
The art of rhetoric (the skill of persuasive speaking and writing) goes back to ancient Greece. Thinkers like Aristotle studied what makes an argument convincing. They discovered that how you end your argument is just as important as how you begin it.
So here's the big question: How do you write a concluding statement that truly wraps up your argument and leaves your reader nodding in agreement? That's exactly what this lesson will teach you.
Core Principles of a Strong Conclusion
A concluding statement is the final sentence or section of your argument essay. It does two important jobs: it follows from your argument (meaning it connects logically to everything you've already said) and it supports your argument (meaning it strengthens your overall claim). Let's break down the key principles.
Restate Your Claim
Summarize Key Evidence
Connect Back Logically
Leave a Lasting Impression
The Anatomy of an Argument Essay Conclusion
Let's look at how a concluding statement fits into the bigger picture of an argument essay. The diagram below shows the structure of a complete argument essay, with the conclusion highlighted at the bottom.
As you can see, the conclusion doesn't stand alone. It's built on the foundation of your entire essay. That's what "follows from and supports the argument" means. Your ending should feel like a natural result of everything the reader just read.
How It Works: Building a Conclusion Step by Step
Writing a strong conclusion isn't magic — it's a process. Let's break down the three-part formula that will help you craft a conclusion every time.
Part 1: Restate Your Claim
Start by reminding the reader what your main argument was. But here's the trick: don't copy your thesis word-for-word. Rephrase it. Use different vocabulary. Show that your argument has grown stronger after all the evidence you presented.
Part 2: Summarize Your Key Evidence
Next, briefly mention your strongest reasons. You don't need to repeat all the details — just give the reader a quick reminder. Think of this like a movie trailer that shows the best scenes. Use transition words like "as shown," "the evidence demonstrates," or "clearly" to connect your summary to your claim.
Part 3: Leave a Lasting Impression
This is your mic-drop moment. You can end with a call to action (telling the reader what to do), a thought-provoking question, or a big-picture connection that shows why your argument matters in the real world.
Conclusion Strategies: What Works and What Doesn't
Not all conclusions are created equal. Let's look at the different ending strategies you can use, and compare them to common mistakes students make.
Notice how every strong strategy on the left side connects back to the argument. That's the key difference. The mistakes on the right either disconnect from the argument, weaken it, or simply don't try hard enough.
Worked Example: Writing a Conclusion
Let's walk through writing a conclusion for a real argument essay. Our topic is: "Students should be allowed to use phones during lunch."
Notice how this conclusion doesn't introduce any new facts or statistics. Every idea in it follows from the body paragraphs and supports the original claim. That's exactly what CCSS.W.7.1.e asks you to do.
Strong vs. Weak Conclusions: A Side-by-Side Look
The best way to understand what makes a conclusion strong is to compare it with a weak one. Let's look at two conclusions for the same essay topic: "Homework should be limited to 30 minutes per night."
| Feature | Weak Conclusion | Strong Conclusion |
|---|---|---|
| Restates the claim? | "In conclusion, I think homework should be limited." (Too vague) | "Limiting homework to 30 minutes gives students the balance they need to succeed." (Clear and rephrased) |
| Summarizes evidence? | "There are many reasons for this." (No specifics at all) | "Research shows shorter assignments improve focus, reduce stress, and leave time for activities that build well-rounded students." (Specific) |
| Lasting impression? | "That's why I think this." (Falls flat) | "When schools respect students' time outside the classroom, everyone wins." (Powerful and memorable) |
| Follows from the argument? | Barely. It doesn't reference the essay at all. | Yes! Every sentence connects to the body paragraphs. |
Looking Ahead: Conclusions in Advanced Writing
The skills you're learning now will grow with you. In high school and college, conclusions become even more important. Let's see how 7th grade conclusions compare to what you'll write later.
| Feature | 7th Grade (Now) | High School & Beyond |
|---|---|---|
| Length | 3–5 sentences | A full paragraph or even a multi-paragraph section |
| Claim | Restate your claim in new words | Synthesize your argument into a broader insight |
| Evidence review | Quick summary of top reasons | Show how all evidence works together to prove a complex point |
| Ending strategy | Call to action or thought-provoking question | Implications, predictions, connections to larger debates |
The great news is that the foundation stays the same. Whether you're writing a 7th grade essay or a college research paper, your conclusion always needs to follow from and support the argument you've built. Master it now, and you'll have a skill that serves you for life.
Practice Problems
Now it's your turn! Try these five problems. They start easy and get more challenging. For each one, think about the three parts of a strong conclusion: restate the claim, summarize evidence, and leave a lasting impression.
Wrapping It All Up
A strong concluding statement does three things: it restates your claim in fresh words, it briefly summarizes your strongest evidence, and it leaves a lasting impression through a call to action, a thought-provoking question, or a big-picture connection. The key rule from CCSS.W.7.1.e is that your conclusion must follow from and support the argument you've already made — never introduce new evidence, and never weaken your claim.
Remember: avoid common mistakes like copying your thesis word-for-word, adding brand-new evidence, or ending with vague phrases like "that is why I think this." Use transition words to connect your ideas smoothly, stay confident in your argument, and end on a note that makes your reader think. A great conclusion is like the final note of a song — it makes everything before it sound even better.
