Give Every Paragraph One Clear Job
A paragraph is a small argument
A paragraph is easier to revise when it makes one promise and keeps it. Imagine a student writing about whether a school should extend its library hours. “The library is useful” names a topic, but it does not yet tell the reader what the paragraph will prove. A more workable point is: “Keeping the library open after school would help students who cannot study comfortably at home.” Now each supporting sentence can explain access, quiet, or time. The paragraph has a direction, and the writer can test whether each detail advances it.
Develop the point in steps
Start by explaining the reason behind the claim: some students share crowded rooms or have responsibilities that make an earlier visit difficult. Then add a specific, supportable detail, such as a school schedule or a student survey if one is available. Explain the connection: an additional hour matters because it creates a predictable place to finish work. Evidence does not explain itself. A reader needs the sentence that tells why this detail supports the point. This is the difference between placing a fact beside a claim and reasoning from the fact.

“Evidence does not explain itself. A reader needs the sentence that tells why this detail supports the point.”
The example makes the writer’s reasoning visible instead of letting a fact stand in for analysis.
Make the sentence order visible
Suppose the paragraph jumps from library hours to book collections and then to homework deadlines. Those ideas may all belong in an essay about libraries, but they do not necessarily belong in one paragraph. Keep the access argument together. A useful sequence is claim, explanation, evidence, interpretation. Repeat a key term such as “access” where it helps readers track the idea; use a transition only when it names a real relationship, such as cause, contrast, or consequence. “Therefore” cannot repair a missing reason.
Revise by checking the promise
Read the first sentence, then summarize the paragraph in a few words. If the summary is “after-school access,” mark any sentence about collection size for a later paragraph. Next, underline the evidence and circle the explanation attached to it. If the evidence has no explanation, add one; if the paragraph makes a claim but offers no evidence, identify what source or observation could support it. Purdue OWL describes unity, coherence, topic sentences, and adequate development as useful paragraph features, while also recognizing that a topic sentence can appear in different positions. Treat the sequence here as a reliable drafting choice, not an inflexible law.
The paragraph’s job
A strong paragraph does not need to contain every relevant thought. It needs to make one contribution to the essay’s larger argument and give readers enough reasoning to see that contribution. When a paragraph feels crowded, the solution may be a new paragraph, a narrower point, or a clearer explanation—not another transition. Revising for unity is therefore a reasoning task: decide what the paragraph is trying to establish, then make each sentence help establish it.
A practical paragraph test
Write a five-word label for the paragraph. Check whether its claim, evidence, and explanation all fit that label. If one sentence needs a different label, move it or give it a new paragraph. Cite evidence where needed, and explain the inference in your own words.
Try it
Revise a paragraph about a school garden that shifts among student responsibility, science lessons, and cafeteria food. Give each idea a separate five-word label, choose one as the paragraph’s focus, and write a claim, one piece of evidence you would need, and a sentence explaining the connection.
Try the idea.
Identify the sentence that does not support a paragraph about library access. Move it or revise the focus, then explain your choice.
See the self-check +
A sentence about book collection size may be relevant to libraries but does not automatically support after-school access. Move it to a paragraph about resources, or broaden the focus and add reasoning that connects both ideas.
