If you wanted to find the main idea in a piece of writing, where would you look?

The main idea is the point of the paragraph. It is the most important thought about the topic. To figure out the main idea, ask yourself this question: What is being said about the person, thing, or idea (the topic)? The author can locate the main idea in different places within a paragraph. In the first sentence is where majority main ideas are found. There's no one place where the main idea is always found.
