Is your child saying “tar” instead of “car”? Are you a speech-language pathologist or parent looking for strategies to teach the tricky /k/ sound?
Most children master the /k/ sound by around 3.5 years of age, but some need a little extra help. In this blog post, you’ll find evidence-based speech therapy techniques, fun activities, and tools to support your child or students in producing the /k/ sound correctly.

How to Teach the /K/ Sound: Preparation Tips
Before diving into saying the /k/ sound, we want to make sure they grasp the concepts of front and back, which can be a bit abstract.
How to Explain Front vs. Back Sounds When Teaching the /K/ Sound
Start by introducing the concept of front and back using familiar toys like farm animals, teddy bears, or puppets. For example:
“Can you show me the front of the cow? Now the back?”
Then move on to their own body: “Show me the front of your body. Now the back.”
Once this concept is clear, explain that:
The /k/ sound is made at the back of the mouth, with the back of the tongue lifting up.
The /t/ sound is made at the front of the mouth, with the tongue tip going up.
Use visuals like a mouth model or pictures to demonstrate. Reinforce that /k/ is a “back sound” while /t/ is a “front sound.”
Auditory Discrimination Activities for /K/ vs. /T/ in Speech Therapy
When a child consistently says /t/ for /k/ (e.g. “tar” for “car”), they may be displaying a phonological process called velar fronting. Start with auditory discrimination activities to help them hear the difference.
Try using:
Minimal pairs cards (e.g. key/tea, car/tar)
Ask them to point to the word you say in random order e.g. tea, tea, key, tea, key
Use magnetic chips and a wand, bingo daubers, or a sorting activity to turn it into a game
No-prep option:
Download the Minimal Pairs Arcade Lite app and select:
Fronting → T/K
Play Feed the Tiger or Balloon Pop for interactive discrimination practice
If a child struggles to hear the difference between /k/ and /t/, continue with discrimination before working on speech production.
Speech Therapy Techniques for Eliciting the /K/ Sound
Once the child understands the concept and can discriminate the sounds, begin eliciting the /k/ sound using the following techniques.
Modelling the /K/ Sound: Using Exaggerated Speech to Improve Pronunciation
Sit face-to-face and use exaggerated models of the /k/ sound:
Open your mouth wide
Say: /k/, /k/, /k/
Encourage the child to watch your mouth and copy
Sometimes visual and auditory models are enough to help a child begin producing the sound.
Using Physical Cues to Teach the /K/ Sound: Tongue Depressor or Spoon Trick
Some children need tactile support to keep the tongue tip down.
Try this:
Use a tongue depressor or teaspoon to gently press the tongue tip down
While holding it down, have them try to say /k/
Most children who substitute /k/ with /t/ will produce a correct /k/ this way. Practice this until the child gets used to the sensation.
Fun Ways to Teach the /K/ Sound: Try the Cereal Trick
Use a cereal loop (like Cheerios or Fruit Loops) to keep the tongue tip down:
Place the cereal behind the lower front teeth
Ask the child to hold it there with their tongue
Say /k/, /k/, /k/
When finished, they can eat the cereal as a reward. This technique is both fun and effective.
Best Books for Practicing the /K/ Sound at Home or in Therapy
Books with repeated /k/ sounds can increase your child’s exposure. Look for books where /k/ appears in initial, medial, or final word positions.

How Lying Down Can Help Kids Say the /K/ Sound Correctly
Some children find it easier to make the /k/ sound when lying on their back. Gravity naturally pulls the tongue toward the back of the mouth, making the correct tongue position easier to find.
Let the child lie down and try saying /k/ while relaxed.
Final Tips for Teaching the /K/ Sound in Speech Therapy
The /k/ sound can be tricky, especially for children with phonological patterns like velar fronting. Remember:
Always start with auditory discrimination to check if the child can hear/discrimate between the /k/ sound and the error sound they are using
Use fun and motivating practice tools
Be patient — back sounds often take time!
