A summary is a short statement that gives the main ideas of a selection. It does not include all of the details as in a retelling. The essence is that it is brief; it focuses on key ideas of the text. Readers condense information into a summary of key ideas to reveal their level of comprehension. In order to summarize a text, readers filter out less significant or repetitious details, identify a general term for a list of specific details, combine ideas into a broad category, and create a sentence that reveals the key focus.
