Which of the following is a skill within phonemic awareness?

• A. Isolation
• B. Syllable counting
• C. Onset-rime
• D. Rhyming

Answer: (A)

Phonemic awareness centers on hearing and working with the smallest units of sound in spoken language, the phonemes. Isolating a sound means identifying a single phoneme in a word—like picking out the initial sound in “bat” (/b/) or the final sound in “cup” (/p/). That direct focus on a single sound is exactly what isolation practices, so it fits squarely as a phonemic-awareness skill.

Syllable counting, rhyming, and onset-rime involve larger sound units or patterns longer than a single phoneme. Syllable counting looks at chunks of sound, rhyming compares the end sounds of words, and onset-rime deals with the initial sound plus the remaining sound together. Those are important early-literacy skills, but they operate at levels beyond the individual phoneme, which is why isolation is the best fit here.
