How to write an informational summary?

Writing a summary is an opportunity to demonstrate your understanding of a text. A summary challenges you to use your own words to condense the main idea and most important details of the original piece. According to the Santa Monica College Reading Center, a summary "does not have to be long nor should it be long." The five-finger summary is an effective method to write a summary that is informative and succinct.
Read the original work at least two times. After the first read, make an outline of important details as you read. Pay attention to topic sentences and concluding sentences; the first and last sentences of a paragraph, and the first and last sentences of a written work.

Read over your outline. Isolate the main idea and the three most important details.

Write a five-finger summary: in the first sentence, introduce the title, author and main idea of the text. Describe the three most important details in one sentence each. Write a concluding sentence that expounds upon and echoes the main idea sentence.

A summary should only include the important of main details of the text. You should always put in the title, author, evidence from the passage, and transition words. Don't forget good grammar! Summaries should always be quick and snappy, no more than 6-8 sentences.
