Lesson 9 — Writing a Topic Sentence

Summary

Learners learn to write a strong topic sentence — the first sentence that tells the reader what the paragraph will be about — and practice the check, “does it tell what my paragraph is about?”

Objectives

• Write a paragraph with a topic sentence, at least two supporting details, and a closing sentence. (D04.S3.03.01)

Connection

Think of a door to a house: the door tells you what kind of place you are about to enter. A topic sentence is the door to a paragraph — it tells the reader, in one sentence, what the whole paragraph will be about. Without it, the reader walks into a room blind. In every language and every writing system, a clear first sentence opens the door for the reader.

Materials

• A topic to write about (a place, an animal, a task, a game)
• A paragraph frame (with the first line highlighted)

Preparation

• Choose a few friendly topics learners know well.
• Prepare the paragraph frame.
• Have paper and pencils ready.

Facilitator note

This lesson is written to the learner (“you”) so it works in a classroom and for a self-directed learner. Writing a topic sentence is a foundational skill, so teach it explicitly: model a strong topic sentence, contrast it with a weak one, then guide practice (Kirschner, Sweller & Clark, 2006). The one check to protect: “does it tell what the paragraph is about?” A strong topic sentence names the topic and gives the reader a clear picture of what is coming. Learners write in their home language and their own writing system — script-agnostic, no Latin alphabet assumed. A learner who is Deaf or hard of hearing writes, signs, or dictates the sentence; the thinking is the writing. A learner who is blind or has low vision composes by dictation, on a braille writer, or by typing and listening back — the thinking is the writing. Celebrate a clear, honest topic sentence in any wording; there is no single “correct” sentence.

Procedure

1. Gather (5 min). Think of a door you know. Before you open it, you already know a little about what is inside. A topic sentence is a door like that.
2. Meet the topic sentence (10 min). Learn: a topic sentence is the first sentence of a paragraph, and it tells what the paragraph is about. It names the topic and gives a clear picture. Try the check: does it tell what my paragraph is about?
3. Watch a worked example (10 min). The facilitator writes a weak sentence — “It is nice.” — then a strong one — “My grandmother’s garden is full of color in the morning.” Watch how the strong sentence opens a door the reader can see through.
4. Write your topic sentence (15 min). Choose a topic you know well. Say your topic sentence aloud first. Then write it on the highlighted line. Read it back and ask: does it tell what my paragraph is about? Fix it if not.
5. Share (5 min). Read your topic sentence to a partner. The partner guesses: “So your paragraph will be about…?” and you say yes or fix it.
6. Close (5 min). One clear sentence, and the reader is in. That is the door, and you wrote it.

Differentiation

• Support: Provide a sentence starter — “My paragraph is about…” or “One thing I love is…” — and let the learner finish it.
• Support (non-speaking): Sign, dictate, or point to a picture and have the topic sentence written or typed.
• Support (blind/low vision): Compose by dictation, on a braille writer, or by typing and listening back; the thinking is the writing.
• Extension: Write two topic sentences for the same topic and choose which opens the door more clearly, saying why.

Assessment

• Formative (observation): Can the learner write a topic sentence that tells what their paragraph will be about, in their own language and writing system?

Home connection

Choose something at home you know well — a meal, a place, a pet — and write one topic sentence about it. Read it to someone and ask, “Do you know what my paragraph will be about?”
