If you teach elementary or middle-grades writing, you already know this trio shows up in red pen more than almost any other error. The reason is baked into the words themselves. There, their, and they're are phonetically identical, so a student's ear gives no clue about which one belongs in a sentence. Only grammar tells them apart: there is an adverb of place, their is a possessive pronoun, and they're is the contraction of they are. Because the distinction is grammatical rather than sound-based, students can't hear their way to the right answer, and that's exactly why targeted there their they're worksheets earn a permanent spot in your ELA toolkit.
Match Worksheet Difficulty to Your Grade Band
Younger students do best with sentence-level fill-in-the-blank items and picture support, where the cognitive load stays on choosing the right word rather than decoding the whole sentence. Upper-elementary students need editing and revision tasks: paragraphs seeded with errors that they have to catch, correct, and justify. That progression mirrors how the standard itself scales.
According to Teach Starter's breakdown of CCSS.ELA-LITERACY.L.4.1.G, the Grade 4 language standard explicitly requires students to correctly use frequently confused words, and it names there, their, and they're alongside to, too, and two as its model example, making this homophone set a formally assessed writing convention by fourth grade.
Knowing where your students sit against that standard tells you which worksheet format to reach for. Grade 2 practice, aligned to the L.2.4 word-study strand, keeps the focus on recognition; by grade 4 the same skill has to live inside independent editing.
Classroom Implementation
Worksheets work best when they anchor a short cycle rather than stand alone. Open with a five-minute mini-lesson that isolates one word at a time, then move to a whole-class worksheet on the document camera so students hear peers reasoning aloud. Reserve the tricky mixed-practice sheet for the next day, once the vocabulary of "possessive" and "contraction" is familiar.
For students who still confuse the words in grades 4 and 5, pull a small group. Give them a shorter, higher-frequency worksheet and sit beside them while they explain each choice. The goal isn't a finished page; it's hearing the reasoning so you can catch the exact point where the logic slips. Keep a stack of half-page versions on hand so intervention never waits on new printing.
The highest-leverage move is refusing to let the skill stay trapped on the worksheet. Build a 60-second editing warm-up into your daily routine using one sentence with a planted there/their/they're error. Over a few weeks, students start self-correcting in their own drafts, which is the whole point.
Frequently Asked Questions
1. What grade level should introduce there, their, they're worksheets?
Basic homophone recognition often begins around grade 2 with word-sound work, then the skill is reinforced as a formal writing convention through grades 4 and 5. Introduce recognition early, and expect to revisit application in upper elementary.
2. What's the easiest way to teach the difference?
Teach the job of each word. They're always expands to they are, their always sits in front of a noun to show ownership, and there points to a place and even hides the word here inside it.
3. How can teachers assess mastery beyond a single worksheet?
Use paired pre- and post-assessments with the same short item set, then look at daily editing warm-ups and students' independent drafts. Real mastery shows up when the correct usage transfers into writing students produce on their own.
4. How does this skill align to Common Core?
Per Teach Starter, CCSS.ELA-LITERACY.L.4.1.G requires students to correctly use frequently confused words and names there, their, and they're as its model example, so the skill is a formally assessed grade 4 language standard.
5. How should teachers help students who still struggle in upper elementary?
Pull a small group, use shorter mixed-practice sheets, and have students explain each choice aloud so you can hear exactly where the reasoning breaks. Then anchor the fix with a daily 60-second editing warm-up.
