Read Like This: Central Ideas and Supporting Details in Texts

The central idea is the big idea or the most important message that the author is trying to convey. It is the unifying element of a story, which ties together all of the other elements of fiction used by the author to tell the story. Determining the central idea will help you to understand and analyze what you are reading. The overall central idea of a text emerges through smaller central ideas and supporting key details that are conveyed through the development of the text.

Once you have determined the overall central idea, you can use it to develop a summary, which includes smaller central ideas and supporting key details. Summarizing a text helps to communicate the most important ideas in a clear and concise manner.

After you have written your summary, be sure that you can answer yes to each of the following questions. If you can, you have written a good summary:

• Does it state the overall central idea for the text?
• Does it include the most important central ideas from the different sections in the text?
• Do all of the central ideas included in the summary support the overall central idea?
• Does it include the most important key details that support one or more of the central ideas?
• Does it contain only information from the text?
• Are all the sentences written in your own words?
