How do you write good supporting sentences in a paragraph?

Make sure that they support the topic sentence! One way to check this is to mentally change the topic or main idea into a question - then, just be sure that each sentence in your paragraph answers that question somehow!

When you are composing your paragraph, the best way is to make a list of every fact about the topic. Look up information if you need to! Use lots of detail and make the sentences easy to understand. In this way, you can be sure that each of your sentences will support the topic instead of changing the subject.
