The Hamburger Paragraph
Think of a good paragraph like a hamburger. It has three layers that work together to create something complete and satisfying.
Topic Sentence (Top Bun)
Tells the reader what the paragraph is about. It is the main idea.
Supporting Details (The Filling)
Facts, examples, reasons, or explanations that support the topic sentence. Usually 3–5 sentences.
Concluding Sentence (Bottom Bun)
Wraps up the paragraph by summarising or linking back to the topic sentence.
Writing Strong Topic Sentences
A topic sentence is the first sentence of your paragraph. It tells the reader the main idea of the whole paragraph. A good topic sentence is clear and specific.
Weak Topic Sentences
- ✗ "Dogs are cool." (too vague)
- ✗ "I will talk about sport." (tells, does not show)
- ✗ "Stuff happened." (unclear)
Strong Topic Sentences
- ✓ "Dogs make wonderful pets because they are loyal and loving."
- ✓ "Playing team sports helps children develop important social skills."
- ✓ "The Great Barrier Reef is one of Australia's most precious natural wonders."
Supporting Details
Supporting details are the sentences that explain, prove, or give examples for your topic sentence. There are different types:
Facts
"The Great Barrier Reef stretches over 2,300 kilometres along the Queensland coast."
Examples
"For example, it is home to more than 1,500 species of fish, including clownfish and parrotfish."
Reasons
"This is important because the reef provides food, shelter, and breeding grounds for countless marine creatures."
Descriptions
"The coral displays brilliant colours — vivid blues, bright oranges, and soft pinks — creating an underwater rainbow."

Worked Examples
See how topic sentences, supporting details, and concluding sentences work together.
Example 1: Complete Paragraph
Playing outside is important for children's health. Physical activity strengthens muscles and bones, helping children grow strong. It also improves mood and reduces stress, making children feel happier after playtime. Studies show that kids who play outside for at least an hour each day sleep better at night. Clearly, outdoor play is essential for a child's physical and mental wellbeing.
Example 2: Identifying the Topic Sentence
Paragraph: "Koalas are fascinating Australian animals. They spend up to 20 hours a day sleeping in eucalyptus trees. Their diet consists almost entirely of eucalyptus leaves, which are toxic to most other animals. Baby koalas, called joeys, live in their mother's pouch for six months. These unique creatures are truly one of Australia's most beloved icons."
Topic sentence: "Koalas are fascinating Australian animals." — This tells us the paragraph will be about why koalas are fascinating.
Example 3: Spotting an Off-Topic Detail
Topic sentence: "Swimming is an excellent form of exercise."
Which detail does NOT belong?
- • "It works every major muscle group in the body." (belongs)
- • "My favourite colour is blue." (does NOT belong — off topic)
- • "Swimming is gentle on joints compared to running." (belongs)
