In onset-rime teaching, the rime of cat, mat and sat is:

1. The onset is the initial sound of the word. 2. The rime is the vowel and the consonant sounds that follow it. 3. In cat, mat and sat, the onsets are c, m and s. 4. What remains in all three is the rime -at. **Why not the others:** The other choices are the initial sounds with a vowel, which are onsets plus a vowel, not the shared rime. _Source: Wikipedia, "Phonics", section "Analytic phonics and analogy phonics" (revision 1379668191)_
