What words signal an opinion?

Best, worst, favorite, boring, beautiful, awful, should, and friends. They're good flags but not a complete test; some opinions wear no flags at all. The reliable test stays the same: can it be checked, or can people disagree?

Is a false statement a fact or an opinion?

A false factual claim ("a week has nine days") is neither a fact nor an opinion; it's a mistake, and checking exposes it. That's the power of the checkable test: it doesn't just sort sentences, it tells you which ones can be caught being wrong.

3rd grade fact vs opinion

3rd grade fact vs opinion worksheets

Third graders sharpen the test on statements where the opinion hides behind confidence: "Mondays are the worst" sounds firm but can't be proven. Spotting judgment words (best, boring, should) and asking "checkable?" turns a feeling-guess into a reading skill.

How to teach this

Hunt the flag words together: best, worst, always-should, boring, beautiful. Then flip one: turn "pizza is the best dinner" into a fact ("pizza has cheese") and a fact into an opinion. Rewriting across the line teaches the line better than sorting alone.

Watch for: An opinion isn't a wrong fact, and a fact isn't a nice opinion; they're different kinds of sentences. 'Broccoli is a vegetable' and 'broccoli is awful' can both be on the same plate. Words like best, worst, should, beautiful, and boring are opinion flags, but the real test is checkability: if no measurement or source could settle it, it's an opinion.
