About Phoneme Substitution
What this skill is
Phoneme substitution requires swapping one sound in a word for another to create a new word (change /c/ in cat to /b/ -> bat, or change short /a/ to short /o/ -> cot).
When children learn it
Phoneme substitution is taught in kindergarten and 1st grade, aligned to K.RF.2.E and 1.RF.2.
Teaching Tips
- Use letter tile tracks to physically swap single letters out.
- Play word ladder games (cat -> hat -> hot -> hop).
Common Mistakes
- Accidentally changing two sounds instead of just the target phoneme.
- Difficulty substituting middle vowel sounds.
