There, Their, and They're: Ending the Homophone Wars at Home
By The Spelling Test team 5 min read
Here's what makes there/their/they're different from every other spelling problem your child has: it will never be caught by sounding out (all three are identical to the ear), it sails straight past most spellcheckers (each word is correctly spelled — just wrong), and it doesn't fade with age on its own (scan any adult comment section). This one has to be fixed, deliberately, or it's for life.
The good news: the fix is small. Five confusable sets cause the overwhelming majority of homophone errors in kids' writing, and each set falls to one test or one anchor. Not twenty rules — five moves.
The master strategy: one anchor per set
Trying to memorize all members of a homophone set equally is what fails. The move that works: anchor ONE member with an ironclad test, and let the others be "everything else." A child who can positively identify they're doesn't need equal mastery of their and there — the triangle collapses once one corner is certain.
Set 1: there / their / they're
Anchor they're first — it has the ironclad test. They're only ever means they are. Expand and listen: "They're late" → "They are late" → works. "We went to they're house" → "to they are house" → nonsense. This is the same expansion test that fixes contractions generally, applied to its most famous customer.
Then anchor their with ownership. Their = belongs to them. The mnemonic that sticks: their contains heir — an heir is someone who inherits things, and their is always about having things.
And there is everything else — places (over there) and the sentence-starter (there is, there are). Bonus anchor if wanted: there contains here, and both are places.
Teach in that order — test, then mnemonic, then default — over three separate weeks, not one laminated chart on day one.
Set 2: your / you're
Same machinery, smaller set. *You're = you are, always, with the expansion test attached: "You're going to love this" → "You are going" → works. "Is this you're bag?" → "you are bag" → caught.
Your is the ownership default. Kids find this pair easier than the triangle — teach it first, in fact, because winning here installs the expansion-test habit that then cracks they're and it's at a discount.
Set 3: to / too / two
Two is free — every child locks the number early (anchor if needed: tw as in twin and twenty).
The real contest is to vs too, and the anchor is too: too = "extra." Extra amount (too loud, too many) or extra inclusion (me too!). The mnemonic writes itself: too has an extra O — the word for "extra" carries a spare letter. Say "the extra O word" a dozen times across a month of casual catches, and it settles. To is everything else, which suits it — it's the workhorse preposition and needs no personality.
Set 4: its / it's
Covered in depth in our contractions guide, but it belongs on this list because it's the set adults lose daily. The short version: *it's = it is, only and always — expansion test — and possessive its gets no apostrophe, matching his and hers. One direction, one test.
Set 5: know / no (and knew / new)
For younger writers, this pair sneaks into everything. The anchor is the silent-K family: know belongs with knee, knife, knock — the K words about... knowing and doing. If your child has met the kn- silent-letter family, this is a free transfer; if not, this pair is a fine excuse to teach it.
How to practice without a single worksheet
Homophones are usage errors, so practice must happen in sentences, by ear:
Sentence dictation. Say a sentence aloud — "They're bringing their dog over there" (the triple crown) — and have your child write it. The ear gives no hints; the tests must fire. Check immediately, celebrate each correct corner separately.
The pause-and-point game. While reading aloud together, stop at any homophone: "Wait — which there is that?" Two seconds, done, reading continues. Twenty of these catches across a month outperform any drill sheet.
Wrong-on-purpose notes. "Your the best kid ever." Leave it on the fridge. The outrage of correcting a parent is a memory adhesive nothing else matches.
Error autopsy, gently. When one slips into their real writing, don't mark it — ask: "Run the test on that one." The child who finds their own you're/your swap is rehearsing the exact skill; the child whose parent circles it is rehearsing being circled.
One caveat on tools: because homophone errors are correctly-spelled words in wrong slots, single-word spelling practice can't catch them — this is a sentence-level skill, which is why the dictated-sentence game above matters more here than any app, ours included. Use audio word practice for the spellings themselves (they're with its apostrophe intact); use sentences for the choosing.
One thing to try this week
Install exactly one test: you're = you are. Catch it four or five times this week in the pause-and-point style — reading, your own texts, a sabotaged fridge note. Nothing else, no charts. Next week, point out that they're works the same way, and watch a second corner fall for the price of half a lesson. The triangle wars end one anchor at a time.
