Which phonemic awareness activity involves replacing a phoneme with another to form a new word?

• A. Phoneme isolation
• B. Phoneme substitution
• C. Blending
• D. Phoneme deletion

Answer: (B)

The key idea is phoneme substitution—the activity where you swap one sound in a word for a different sound to make a new word. For example, take "mat" and replace the initial /m/ with /s/ to say "sat." Or swap the /b/ in "bat" with /k/ to get "kat," which is heard as "cat" when spoken. This shows how changing a single sound changes the word.

Phoneme isolation, in contrast, asks you to identify a single sound within a word, not change it. Blending is about putting sounds together to hear the whole word. Phoneme deletion involves removing a sound to form a new word.
