How to teach the “o” 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 sound /o/.
- Do the gesture. Pretend to turn a light on and off saying o-o-o— kids remember sounds 2× faster when there’s a physical action attached.
- Find it in words. Read the 5 example words aloud slowly, stretching the /o/ sound: “o–n”.
- Spot it around the house. “Can you find something that starts with /o/?” Aim for 3 wins in a row before stopping.
