How to Spell “cog”

Children most often write this word as ocg, cogg, coog. Those errors are useful — each one points to a specific sound the child has not yet connected to a letter.

1. Start with the picture: <strong>cog</strong> begins with the /k/ sound, so begin with "c".
2. Say the word slowly three times, then write one sound per letter: <strong>c - o - g</strong>.
3. The "o" in <strong>cog</strong> is a short o — the mouth stays wide open, like /ɒ/ in <em>hot</em>.
4. Blend the last two sounds smoothly: <strong>co</strong> + <strong>g</strong> = <strong>cog</strong>.

Phonics Tip for Cog

"cog" and "bog" and "dog" share the ending /ɒɡ/. Say them back to back so the child hears that only the first sound changes. That is the core of the -og family.
