How to teach the “igh” sound

  1. 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 /aɪ/.
  2. Do the gesture. Stretch your arms up high and say igh-igh-igh— kids remember sounds 2× faster when there’s a physical action attached.
  3. Find it in words. Say a few example words aloud slowly, stretching the /aɪ/ sound: “n–i–g–h–t”.
  4. Spot it around the house. “Can you find something that starts with /aɪ/?” Aim for 3 wins in a row before stopping.
