Third grade spelling words
Eighty words in eight units. The year r-controlled vowels arrive, prefixes start doing real work, and homophones become a problem the test itself has to solve.

What the practice modes do
Generated by the same code the buttons run, on the first few words of this list, so what is printed here is what you will get.
| Word | Letter scramble | Missing letters | Spelled out loud |
|---|---|---|---|
| farm | marf | f_rm | F, A, R, M |
| start | atsrt | st_r_ | S, T, A, R, T |
| sharp | hrsap | s__rp | S, H, A, R, P |
| garden | graden | g_rd_n | G, A, R, D, E, N |
When r swallows the vowel
In farm, her, bird, turn and storm the vowel does not say anything you could sound out — the r has taken it over. That is why they arrive together in two units here: there is nothing phonetic left to build on, so the words have to be grouped by spelling and learned as families.
er, ir and ur are the hard part, because all three make the same sound and nothing in the word says which one it needs. er is the commonest by a wide margin, so it is the right guess when a child has to guess. The other two are memory, and there is no honest way to dress that up.
Soft c and soft g, and the letter that decides
Before e, i or y, c says /s/ and g says /j/: city, circle, giant, gentle. Everywhere else they stay hard. This is one of very few English spelling rules with almost no exceptions worth mentioning at this age, and it explains a surprising amount — including why dance needs the e that appears to be doing nothing.
The rule also reads backwards, which is where most of its value sits. A child wanting to write an /s/ sound at the start of a word can rule c in or out by looking at the next letter, instead of choosing between c and s by feel.
Prefixes and suffixes leave the base word alone
un + happy is unhappy. re + read is reread, with both e’s. help + ful is helpful, with one l. The lesson in these two units is not the meanings, which children pick up easily, but the mechanics: bolt the piece on and change nothing. Most errors here are children helpfully tidying away a double letter that belongs.
-ful is the one to state out loud. The suffix has one l, always, even though full has two and even though it sounds exactly like full. Careful, helpful, useful — never carefull.
Homophones need a sentence, not a rule
Unit six is ten words and five sounds: their, there and they’re; to, too and two; hear and here; right and write. No spelling rule can help, because the words are identical in the air. What distinguishes them is what they mean in one particular sentence, and a test that dictates them bare is asking an unanswerable question.
This is the unit that changes how the test has to work. Read there on its own and any of three spellings is defensible. Read "Your bag is over there by the door" and exactly one is. Keep the sentences switched on for this unit whatever you do with the rest of the year.
Common questions
What is the difference between their, there and they’re?
`Their` shows possession — their coats. `There` is a place, or the word that opens a sentence like "there is". `They’re` is they are with the a removed. The test on this page dictates each inside a sentence, because out of context the question has no correct answer.
Why does careful have one l when full has two?
Because `-ful` as a suffix is a shortened form and has always been written with one l, while `full` standing alone keeps both. It is an inconsistency rather than a rule, and the only remedy is to say it aloud once and then test it.
My third grader spells well in tests but badly in stories. Why?
A test asks for one word with full attention; a story asks for four hundred with almost none. The gap is normal and closes as handwriting and sentence construction become automatic. Judge spelling from the test and content from the story, rather than each from the other.
Should third graders still be sounding words out?
For unfamiliar words, always — it is the strategy that generalises. But by third grade the common words should be automatic, and a child still sounding out `because` letter by letter needs those specific words drilled rather than more phonics.
