Fact vs opinion is a key reading skill that helps students understand what a writer is saying and how to respond. A fact can be checked and proven true or false, while an opinion tells what someone thinks, feels, or believes. This cheat sheet helps students sort statements, find evidence, and read more carefully. It is useful for stories, articles, essays, advertisements, and online information. The most important rule is to ask whether the statement can be verified with evidence. Facts often include dates, numbers, names, locations, or results that can be checked. Opinions often use judgment words such as best, worst, beautiful, boring, should, or believe. Readers should also watch for bias, which can make information seem one-sided or unfair.

Key Facts

  • A fact is a statement that can be proven true or false with evidence.
  • An opinion is a statement that shows a belief, feeling, judgment, or personal preference.
  • Decision rule: If a statement can be checked using reliable evidence, it is a fact.
  • Decision rule: If a statement depends on what someone thinks or feels, it is an opinion.
  • Facts often include specific details such as numbers, dates, measurements, names, or places.
  • Opinions often include clue words such as best, worst, favorite, should, believe, think, beautiful, or boring.
  • Evidence is information that supports a claim, such as a quote, statistic, example, observation, or expert statement.
  • Bias means a writer favors one side or viewpoint, so readers should check the facts and look for missing information.

Common Mistakes to Avoid

  • Calling a statement a fact because it sounds true is wrong because facts must be checked with evidence, not guessed.
  • Calling every statement with numbers a fact is wrong because numbers can be used in opinions or misleading claims.
  • Thinking an opinion is always false is wrong because opinions can be reasonable, but they still depend on personal judgment.
  • Ignoring clue words such as best, should, or favorite is wrong because these words often signal an opinion.
  • Trusting a biased source without checking other sources is wrong because bias can leave out facts or present only one side.

Practice Questions

  1. 1 Label the statement as fact or opinion: The school library has 2,430 books.
