Summarizing and paraphrasing help students understand, explain, and use information from texts. This cheat sheet shows how to shorten a passage into its most important ideas or restate a source in fresh words. Students need these skills for reading responses, research projects, essays, and class discussions. Strong summaries and paraphrases show understanding without copying the original text. A summary gives the main idea and key details in a shorter form, while a paraphrase restates a specific idea in about the same level of detail. Both should use your own words, keep the original meaning, and avoid personal opinions unless the assignment asks for them. A useful summary follows the pattern somebody, wanted, but, so, then for stories or topic, main idea, key details for nonfiction. A good paraphrase changes sentence structure and wording while still giving credit when the idea comes from a source.

Key Facts

  • A summary is a shorter version of a text that includes the main idea and only the most important details.
  • A paraphrase restates a specific sentence, paragraph, or idea in your own words while keeping the original meaning.
  • Summary formula for nonfiction: topic + main idea + 2 or 3 key details = concise summary.
  • Summary formula for fiction: somebody + wanted + but + so + then = story summary.
  • Paraphrase formula: read + cover + restate + compare + cite = accurate paraphrase.
  • A summary should usually be much shorter than the original text, while a paraphrase may be close to the original length.
  • Do not add opinions, new examples, or extra facts when summarizing or paraphrasing a source.
  • If the idea, facts, or wording came from a source, give credit according to the citation style your teacher requires.

Vocabulary

A brief retelling of a text that includes the main idea and the most important details.

Common Mistakes to Avoid

  • Copying the original sentence and changing only a few words is wrong because it is too close to the source and may count as plagiarism.
  • Including every detail in a summary is wrong because a summary should focus only on the main idea and key supporting details.
  • Adding personal opinions to a summary is wrong because summaries should report what the text says, not what the writer thinks about it.
  • Changing the meaning while paraphrasing is wrong because a paraphrase must stay accurate to the original idea.
  • Forgetting to cite a paraphrase is wrong because borrowed ideas still need credit even when the wording is your own.

Practice Questions

  1. 1 A 600-word article explains three causes of water pollution: factory waste, farm runoff, and litter. Write a 2-sentence summary that includes the main idea and all three causes.
  2. 2 A paragraph has 180 words. Your teacher asks for a summary that is about one third as long. About how many words should your summary be?
  3. 3 Paraphrase this sentence without changing its meaning: Many animals migrate to warmer places when winter reduces their food supply.
  4. 4 Explain why a paraphrase still needs a citation even if none of the original words are copied.
