3rd Grade Commonly Confused Words Worksheets
Commonly confused words sound the same but do different jobs: their (belonging), there (a place), they're (they are); your and you're; its and it's; to, too, and two. Third graders learn to slow down and pick the word that matches the meaning, since spelling alone can't help.

How to teach this
Teach the expansion test first: if the word has an apostrophe, say the two words out loud in the sentence. "They're boots by the door" becomes "they are boots," which sounds wrong, so it isn't they're. For their/there, anchor each to a cue: their has "heir" (ownership), there has "here" (place). One set per session; mixing too early muddies all of them.
Watch for: Spellcheck won't catch these: 'there boots' is spelled correctly, it's just the wrong word. The apostrophe versions are always two words squeezed together: they're = they are, you're = you are, it's = it is. Expanding them is the test.
Common questions about commonly confused words
- How do I teach their, there, and they're?
- One meaning at a time. Their owns things (their boots). There points to a place (over there; notice "here" inside it). They're is "they are" squished together; if you can say "they are" in the sentence, it's they're. Then mix all three on a worksheet to test the sorting.
- Why can't spellcheck fix these mistakes?
- Because every option is a correctly spelled word. "The twins left there boots" passes a spellchecker; it just means the wrong thing. That's exactly why these words need deliberate practice rather than editing tools.
