First move
Give the paragraph one job
Before adding evidence, decide what this paragraph is trying to prove. The topic sentence should name that one job.
- 1Write the paragraph claim in one sentence.
- 2Check that it supports the thesis, not just the general topic.
- 3Make sure every piece of evidence in the paragraph fits that sentence.
Prompt clues to look for
"Develop your argument in organized paragraphs"
Each paragraph needs its own smaller claim.
Your move: Write topic sentences that work like sub-claims under the thesis.
"Use clear transitions"
Your reader needs to see how one paragraph leads to the next.
Your move: Start with a phrase that shows the relationship, then state the new claim.
"Explain one reason per paragraph"
The paragraph should not try to prove everything at once.
Your move: Split paragraphs when you have two different reasons or evidence types.
What it looks like
Topic only
This paragraph is about poverty and education.
This names the subject, but it does not say what the paragraph will prove.
A topic sentence needs a claim, not a label.
Mini-claim
Limited access to transportation makes rural students miss school more often, widening achievement gaps before graduation.
This gives the paragraph a specific job and points toward the evidence it needs.
Strong topic sentences are thesis helpers.
Common mix-ups
A topic sentence is just a transition.
A transition connects paragraphs. A topic sentence states the new paragraph claim.
Fix: Use both if needed: "Beyond cost, transportation also limits access..."
The first sentence can be vague because the evidence will explain it later.
Vague starts make the reader work too hard.
Fix: Name the point before giving evidence.
Every topic sentence must preview exactly one quote.
It should preview the claim, not the citation.
Fix: Write the argument first, then choose evidence that proves it.
Frequently asked questions
Does every body paragraph need a topic sentence?
In high school academic writing, yes. The topic sentence tells the reader what the paragraph is proving and keeps the evidence from feeling random.
Can a topic sentence be a question?
Usually no. A topic sentence should answer a question, not ask one. Turn the question into the claim the paragraph will prove.
How is a topic sentence different from a thesis?
The thesis controls the whole essay. A topic sentence controls one paragraph and should support one piece of the thesis.
