A short student paragraph about bees is shown first as a muddled draft that opens with a detail, has a stray sentence about a dog, and simply stops, then rebuilt as a good paragraph with a topic sentence, two supporting sentences and a closing sentence, each lit in its own colour. Three boxes on the right name the parts under the rule "one paragraph, one main idea", and a final line explains that the dog is a new idea and so gets a new paragraph of its own.

What the lesson says

What makes a good paragraph?

Here is a student's first try at a paragraph about bees.

It is hard to follow, because no sentence tells the reader the main point.

And the dog is a different idea, so it does not belong in this paragraph.

A good paragraph is about one main idea.

And it usually has three parts.

A topic sentence tells the reader the main idea, usually first.

Supporting sentences give details that explain or prove it.

A closing sentence wraps the idea up.

Here is the same paragraph, rebuilt.

The topic sentence comes first: bees are important to our food.

Two supporting sentences explain how: they carry pollen, and then the plants can make fruit.

The closing sentence wraps it up: without bees, we would have less food.

The dog is a new idea, so it gets a new paragraph of its own.

A good paragraph has one main idea, with a topic sentence, supporting details and a closing sentence.
