Many Teachers Use Onsets and Rimes to Improve the Word

Many teachers use onsets and rimes to improve the word identification skills of their students. Why is this?

A) It makes sense to teach onsets and rimes because most students are not able to recognize the number of phonemes in a word.
B) Once students know the definitions of onset and rime, they can determine which syllables have an onset and a rime, and which have only a rime.
C) Of all the word identification strategies available for students to use, phonics is the least effective.
D) The most common rimes appear repeatedly in English words.
