Teach TH To Your Child

You are going to teach the voiced and voiceless TH sound to your child here and then practice this skill at the syllable level. Your child will learn how to say TH correctly in the beginning, medial, and end of syllables. If you are just starting your home practice for TH, this is a very important first step.

Teach TH With a Mirror

I like to start the teaching phase with a mirror. This technique works well for most children. If your child is distracted by it, remove it. You can follow each step simply by looking at each other.

TH is a visual sound which means that your child can easily see how to say it by looking at you. Bring attention to your face as much as possible during these practices.

Mirror Game

Materials: A mirror and the TH syllable list

How to do activity:

1. Sit down at a table with your child. Get out a portable mirror. If you don't have a portable mirror, sit in front of any mirror in your house.

2. Talk about how your tongue sticks out between your teeth when you say the TH sound. Demonstrate and have your child copy.

3. Now, with tongue slightly protruding past teeth, blow air gently with your voice box on (buzzing) and off (not buzzing). Have your child imitate you.

4. Talk about how it feels and practice this for a few turns. 

5. Once your child has mastered this position, move on to practicing syllables from the syllable list below with this same technique.

6. Play with which cues work best for your child as you move through the list.

7. If your child is having a hard time saying TH in syllables (which is common with this sound), focus your practice on "tha." Do an exaggerated TH and the slowly bring your tongue straight back for the "a." Make sure not to stop your airflow. Have your child copy this and make sure their teeth don't touch their lips (as in the F sound)!

Helpful Tips:

  • Bring attention to your lips when possible. I like to point.
  • Ask your child to "stick out tongue"


Work on syllables for a few minutes a few times a day or until your child learns how to say them correctly. Aim for about 80%


Don’t forget to fill out the syllable chart above so you can remember what you tried and how it went!

Your child may learn TH syllables quickly. When your child is saying TH right most of the time, about 80%, quickly move on to the word level!
