Commonly Confused Words Worksheets
By 4th grade, the confusion sets grow to include then/than, were/we're/ where, whose/who's, and through/threw, matching the grade-4 standard on frequently confused words. The reliable tools are expanding contractions ("they're" = "they are") and asking what the sentence actually means.

What students need to know
Some words sound alike but mean different things: their, there, and they're are three different words.

Commonly Confused Words across the grades
3rd Grade
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.
4th Grade
By 4th grade, the confusion sets grow to include then/than, were/we're/ where, whose/who's, and through/threw, matching the grade-4 standard on frequently confused words. The reliable tools are expanding contractions ("they're" = "they are") and asking what the sentence actually means.
5th Grade
Fifth graders tackle the pairs that trip adults: affect and effect, principal and principle, accept and except. The sound-alikes now differ by part of speech and shade of meaning, so choosing well means reading the whole sentence's intent, not just the blank.
6th Grade
Sixth graders handle the full gallery of confusables in academic-length sentences, where a wrong choice changes the claim: the study's effect versus what affected it. Precision with these pairs is a quiet marker of polished writing, and graders notice.
