Ck Words
Ck is two letters for one sound, the same sound as k, and it goes straight after a short vowel. Duck, back, sock. Below are the ck words by family, the rule in one line, free worksheets and the games that make it stick.

Ck is a digraph, two letters that spell one sound, and the sound is just k. There is no c sound and no separate k sound in back: it is b, a, ck, three sounds in four letters.
What makes ck worth its own page is not the sound, it is the choice. Your child already knows what k says. What they have to learn is when a word takes ck and when a plain k will do, and that is a rule with a shape they can use.
When do you use ck instead of k?
Ck goes straight after a short vowel at the end of a word. Everywhere else, a plain k does the job.
- ck after a short vowel: duck, back, sock, neck, kick
- k after a consonant: milk, desk, task
- k after two vowels together: book, week, look
That is the whole rule, and it holds well enough to teach as a rule rather than as a tendency. Say the vowel before the /k/ sound: if it is short and there is nothing between it and the /k/, the word takes ck.
The sheet that practises the choice lives on the 1st grade spelling list, at -ck and -k words, where the two endings sit in facing columns and a spelling sheet checks whether the choice sticks. This page does not repeat it. What this page has is the ck words themselves, family by family, which is what a child practises once the rule is understood.
Ch has a twin of this rule, and it is worth knowing they behave the same way: after a short vowel you write tch, and everywhere else ch. Catch and match, but lunch and beach. The ch word list covers it.
What are the easiest ck words for a beginner?
Start with one family and three sounds. The five families below each share an ending, so a child who can read one word in a family can usually read the rest of it, which is the fastest early win there is.
The order that works is roughly -ack, -ick, -ock, -uck, -eck, easiest first. Back, pack and sack are the most familiar; -eck is last because English has fewest of them and several (wreck, speck) are words a six-year-old rarely meets.
A child is ready for these once they can read cat, hop and bed without stopping to work them out. The only new thing in back is that the last two letters make one sound.
How do you teach ck words?
One family at a time, and read before you write.
- Say the family out loud. Back, pack, sack, tack. Let your child hear that only the first sound changes.
- Read the words on cards, family by family, before mixing them.
- Then spell them. Say a word and have your child write it. This is where you find out whether the ck is really known, because nothing in the sound tells them the c is there.
- Mix two families only once each is comfortable on its own.
- Find them in a book. Ck words are everywhere in early readers, which makes this the easy step.
Teaching one pattern at a time in a planned order is what the National Reading Panel’s 2000 report calls systematic phonics, and the panel found it helps children from kindergarten through sixth grade.
Helping your child spell ck words, and the mistakes to expect
Two mistakes, and they mean opposite things.
Writing duk for duck is the rule not yet learned. Your child has heard the word correctly and written the sound with the letter they know. Nothing about the sound tells them a c belongs there, so this is not carelessness and it is not a hearing problem. Show them the pattern and practise one family at a time.
Writing bakc for bake, or milck for milk, is the opposite, and it is a better sign than it looks. Your child has learned ck and is applying it everywhere, which is what learning a rule looks like before the exceptions land. The fix is the contrast rather than more ck practice: bake has a long vowel, milk has a consonant in the way, and the -ck and -k sort is the sheet for it.
A third one worth naming: writing ck at the start of a word. Ck never begins a word in English, ever. That one is quick to fix because the rule has no exceptions.
When do kids learn ck words?
Usually in first grade, once short words are solid, and some programs introduce it at the end of kindergarten. It arrives with the other end-of-word spelling patterns rather than with the letter sounds, because it is a choice about spelling rather than a new sound to learn. Common Core RF.1.3a asks first graders to “know the spelling-sound correspondences for common consonant digraphs”, and ck is normally taught alongside them without anyone calling it one.
Where it sits among the other first grade rules is on the spelling rules guide, and the 1st grade spelling list has it in the context of the whole year.
Which words end in -ack?
Every word here ends with the same single sound, spelled ck. Back, pack, sack: only the first sound changes, which is what makes a family the fastest way in.
Start with the first four and stay there until they are easy. Each is three sounds, so the sound boxes give ck one box and the other two letters one each. That is the clearest picture of the pattern your child will get.
The last four add a blend at the front. Black, snack, track and crack are four sounds each, and putting them next to back in the sound boxes shows the difference that matters: bl and cr are two sounds you can hear separately, and ck is one you cannot.

Which words end in -ick?
The -ick family is the biggest of the five, and the one where a child meets the most words they already say.
Chick is the word to point at. It has two letter pairs in it, ch at the front and ck at the back, and only four sounds in five letters: ch, i, ck. A child who can put chick in three boxes has understood the whole idea this page is about.
Kick, lick, pick, sick and tick are the three-sound words to start with. Brick, stick and trick add a blend, and are the step up once the short ones are easy.

Which words end in -ock?
Lock, rock, sock and dock are the three-sound words here, and they are among the first ck words most children read.
Knock is the odd one, and it is worth explaining rather than skipping. The k at the front is silent, so knock has five letters and three sounds: kn, o, ck. Two letter pairs again, one at each end, and only the middle letter doing a job on its own.
Block and clock sound almost alike and are spelled almost alike, which makes them a good pair to practise together once each is solid on its own.

- rock
- sock

Which words end in -uck?
Duck and truck are the two ck words most children can already say and want to read, which makes this a good family to reach early even though it is smaller than -ack and -ick.
Six words is the whole family worth teaching. There are others, but they are words a six-year-old does not use, and a longer list here would be padding rather than practice.
Stuck, truck and cluck each put a blend in front of the short u. Four sounds, five letters: the sound boxes make that visible in a way reading them aloud does not.

Which words end in -eck?
This family is small, and that is the fact rather than a gap in the list. English has far fewer -eck words than -ack or -ick, and most of the rest (wreck, fleck) are words your child will not meet for years.
Neck, deck and peck are the three to know. Check is the useful one, with a ch at the front and a ck at the back, and speck adds a blend.
Leave this family until last. A child who has the other four will read these the first time they see them, because there is nothing new in them.

Climb a ck word ladder
Every word on this ladder ends in ck, and the ck never changes. What moves is the letter in front of it and the vowel in the middle, one at a time, all the way up.
That is the part of ck a first grader still gets wrong. They know the sound; what they are learning is that the two letters travel together as one, and a ladder that swaps everything around them without ever splitting them is five reminders of it in a row.

What comes after ck words?
Ck is a spelling pattern rather than a new sound, so what comes next depends on which part your child found hard.
- If the sound was never the problem and the choice is, the -ck and -k words on the 1st grade list sort the two endings against each other.
- If ck was the first letter pair your child met, the others come next: sh words, ch words and words with th, each with its own lists and sheets.
- Ch has the same rule with different letters: tch after a short vowel, ch everywhere else. The tch word list has those words family by family, the ch word list covers the plain ch, and the 2nd grade -ch and -tch words sort the two against each other.
- The 1st grade spelling list puts ck among the other patterns of the same year.
- Several words on this page start with a blend (black, snack, brick, truck), which is two letters keeping both sounds rather than one letter pair making a new one: consonant blends explains the difference and has a word list per family.
If your child is still working out short words like cat and hop, go back to CVC words first. Ck is easier to learn on top of a solid short word than alongside one.
Frequently asked questions
What are ck words?
Ck words are words where the letters c and k together spell a single sound, the same sound as k on its own. Back, duck, sock and kick are ck words. The two letters make one sound, so back is four letters and three sounds.
When do you use ck instead of k?
Use ck straight after a short vowel at the end of a word: duck, back, sock, neck, kick. Use a plain k everywhere else, which means after a consonant (milk, desk) or after two vowels together (book, week). The rule covers the end of a short word and is one of the most reliable in English.
What are the easiest ck words for a beginner?
Start with three-letter-sound words in one family at a time. Back, pack and sack, then duck, luck and tuck. A child who can read cat and hop is ready for these, because the only new thing is that ck is one sound rather than two.
Why does my child write duk instead of duck?
They have heard the word correctly and spelled the sound with the letter they know. That is the rule not yet learned rather than a mistake about the sound. Show them that after a short vowel the k needs a c in front of it, and practise one family at a time.
Why does my child write bakc or milck?
That is the opposite problem and it is a good sign: they have learned the ck pattern and are applying it everywhere. Bake has a long vowel and milk has a consonant before the k, so both take a plain k. A child over-applying a rule has understood it.
What age do kids learn ck words?
Most children meet ck in first grade, once they can read short words like cat and hop without stopping. Some programs introduce it at the end of kindergarten. It usually comes alongside the other end-of-word spelling patterns rather than with the letter sounds.
Is ck a digraph?
Yes. Two letters spelling one sound is what a digraph is, and ck qualifies. Almost nobody calls it one, though. It is usually taught as a spelling rule, because unlike sh or ch the question a child faces is not what sound it makes but when to use it.
