How to Practice Initial OY Words at Home

Strategies for practicing the OY sound at the beginning of words.

1

OY is a diphthong: the mouth starts in one vowel position and glides to another inside a single syllable. Say the two halves slowly and separately first, then blend them until it is one smooth movement.

2

These words open on the vowel itself, with no consonant in front of it. Say the OY sound on its own first, then carry straight on into the rest of "oil" without stopping in between.

3

Use a mirror. A vowel is made by how open the jaw is and how the lips and tongue sit, not by a contact your child can feel, so watching the mouth is the clearest feedback available.

4

Practice minimal pairs — two words that differ only in this vowel. Hearing the pair back to back shows a child exactly what has to change, which a single word never does.

5

Go by sound, not spelling. English writes the OY sound several different ways, so read the words aloud together rather than teaching them as a spelling pattern.

6

Play "I Spy" with the sound rather than the letter: anything whose name begins with the OY sound counts.
