Learn the “th” sound →How to teach the “th” sound
- Hear it first. Tap Play three times. Have your child watch your mouth while you copy the sound — no letter name yet, just the pure phoneme /θ/.
- Do the gesture. Pretend to be naughty and stick out tongue saying th-th-th— kids remember sounds 2× faster when there’s a physical action attached.
- Find it in words. Say a few example words aloud slowly, stretching the /θ/ sound: “t–h–i–n”.
- Spot it around the house. “Can you find something that starts with /θ/?” Aim for 3 wins in a row before stopping.
