Two ways to organize
| Method | How it works | Best for |
|---|---|---|
| Block (subject by subject) | Paragraph on subject A, then paragraph on subject B, then a paragraph that compares | Short essays, or subjects with few points of comparison |
| Point by point | Each paragraph takes one feature and discusses both subjects | Most school essays; keeps the comparison in front of the reader |
The thesis must make a point
| Weak | Strong | Why |
|---|---|---|
| E-readers and printed books are alike in some ways and different in others. | Both e-readers and printed books let you read anywhere, but printed books are better for studying because they are easier to mark up and flip through. | The weak one is true of any two things. The strong one says what the comparison shows. |
| This essay compares two coming-of-age novels. | Both novels follow a teenager leaving home, but one treats leaving as escape and the other as loss, which changes what growing up means in each. | An announcement is not a claim. |
| Five similarities and five differences, no thesis | A claim the similarities and differences support | Without a point, the essay is just a list. |
Signal words
- Similarity: both, likewise, similarly, also, in the same way, like
- Difference: however, whereas, while, in contrast, unlike, on the other hand
Worked examples
Example 1: plan a point-by-point essay
Problem Topic: printed textbooks vs digital textbooks.
- List features: cost, weight, note-taking, access without internet.
- Find the point: digital is cheaper and lighter, but printed is better for taking notes and works without Wi-Fi.
- Write the thesis: Digital textbooks win on cost and weight, but printed books are still better for deep studying, so schools should offer both.
- Make each feature a body paragraph that discusses both types.
Answer Thesis plus three point-by-point paragraphs: cost and weight, note-taking, offline access.
Example 2: write one point-by-point paragraph
Problem Feature: taking notes.
- Topic sentence that names both: The biggest difference shows up when students take notes.
- Subject A with a detail: In a printed book, students can underline, write in the margins, and flip back to a marked page in seconds.
- Subject B with a contrast word: Digital textbooks offer highlighting too, whereas finding an old note often means scrolling or searching.
- Explain the point: For studying before a test, that speed matters.
Answer One feature, both subjects, a contrast word, and a sentence that says why it matters.
Common mistakes and fixes
| Mistake | Fix |
|---|---|
| No thesis, just a list of similarities and differences | Ask so what? and write a claim about what the comparison shows. |
| Block essay with no comparing at all | Add a section, or sentences in the B paragraph, that link back to A. |
| Comparing different features for each subject | Use the same features for both so the comparison is fair. |
| Choosing subjects with no real connection | Pick two things that share a category or a purpose. |
Practice
Five compare and contrast questions
Which thesis makes a point about a comparison?
- E-readers and printed books are similar and different.
- This essay compares e-readers and printed books.
- E-readers were invented after printed books.
- Both e-readers and printed books let you read anywhere, but printed books are better for studying because they are easier to mark up.
Show answer
Answer: Both e-readers and printed books let you read anywhere, but printed books are better for studying because they are easier to mark up.
It names a similarity and a difference and says what they show. Similar and different is true of any two things, This essay compares is an announcement, and the invention date is a fact with no comparison point.
In point-by-point organization, how is each body paragraph built?
- Around one subject only
- Around one feature, discussing both subjects
- Around one quotation
- Around the conclusion
Show answer
Answer: Around one feature, discussing both subjects
Point by point means each paragraph compares the two subjects on one feature. Covering one subject per paragraph is the block method.
Which word signals a contrast?
- whereas
- similarly
- likewise
- also
Show answer
Answer: whereas
Whereas introduces a difference. Likewise, similarly and also signal that two things are alike or add a point.
Which pair gives the best basis for a compare and contrast essay?
- A novel and the year 1492
- Two novels that both tell a coming-of-age story
- Photosynthesis and a bicycle
- One novel and nothing else
Show answer
Answer: Two novels that both tell a coming-of-age story
They share a category and a theme, so their differences mean something. The other pairs share no clear basis, and one subject alone cannot be compared.
An essay lists five similarities and five differences between two cities but never says what they show. What is its main weakness?
- It has no thesis that explains why the comparison matters.
- It is too short.
- It uses transition words.
- It discusses two subjects.
Show answer
Answer: It has no thesis that explains why the comparison matters.
Without a claim, a comparison is just a list. Length, transitions and having two subjects are not problems; they are expected.
Frequently asked questions
Should I use block or point-by-point organization?
Point by point is usually clearer, because the reader sees both subjects side by side on each feature. Block works for short essays or when each subject needs a lot of background. If your teacher names a method, use that one.
Do I need equal space for both subjects?
Roughly, yes. If one subject gets most of the essay, the comparison feels one-sided. Use the same features for both, and give each a similar amount of evidence, even if your thesis favors one.
Can a compare and contrast essay focus only on differences?
Yes, if the assignment allows it. Many essays mention a key similarity first, because it shows the two subjects belong together, and then focus on the differences that support the thesis. Check whether your prompt asks for both.
