Why do we spell “back” with two letters at the end instead of one? At Mr. Greg – English Teacher, we provide free printable -CK word worksheets to help students master this essential spelling rule.
The -CK digraph is one of the first “complex” patterns children learn. It’s the perfect bridge between simple 3-letter words and more advanced phonics.

What is the -CK Ending Rule?
In English, we have a very specific rule for the /k/ sound at the end of a word.
The Rule: If a one-syllable word has a short vowel (a, e, i, o, u) and ends with the /k/ sound, we almost always use -ck.
Common -CK Words for Kindergarten:
- Duck: A feathered friend that loves to quack and swim.
- Sock: What we wear on our feet before putting on shoes.
- Back: The part of your body behind you, or the opposite of front.
- Lock: What we use with a key to keep things safe.
- Sick: How we feel when we have a cold or a tummy ache.
- Neck: The part of the body that connects your head to your shoulders.
Why are -CK Words Important?
- Introduction to Digraphs: It teaches kids that two letters (c and k) can work together to make just one sound.
- Spelling Confidence: Once kids learn the “short vowel” rule, they stop guessing whether to use a ‘k’, a ‘c’, or ‘ck’ at the end of words.
- Reading Fluency: -CK words are high-frequency words. Mastering them allows children to read common sentences without pausing to decode the ending every time.
Inside Mr. Greg’s -CK Worksheet Pack
Our worksheets use visual and tactile methods to help the -CK rule “click” for young learners:
- The “One Sound” Box: Practice writing ‘c’ and ‘k’ together in one single sound box to reinforce that they make one sound.
- Short Vowel Detectives: Look at a word and determine if the vowel is short. If it is, add the -ck!
- Rhyme Time Matching: Draw lines between rhyming -CK words like duck and truck or lock and sock.
- Sentence Building: Practice reading and writing simple sentences like “The duck is on the rock.”
5 Fun Ways to Practice -CK Words
- The “Quack” Game: Every time a student reads a word ending in -uck (like duck, luck, or buck), they have to “quack” like a duck!
- Lock and Key: Write -CK words on paper “keys.” To “unlock” a toy box, the student must read the word on the key correctly.
- Sock Sorting: Bring in a bunch of colorful socks. Hide -CK word cards inside the socks and have students go on a “sock hunt” to find and read them.
- Back-to-Back Writing: Have two students sit back-to-back. One student “writes” an -CK word on the other’s back with their finger, and the other has to guess the word.
- Build a Block: Use LEGO or building blocks. Write “c” on one block and “k” on another. Snap them together every time you finish a word to show they are a team.
