Teachers should remember that students are still developing an ear for the various parts of words and the sounds they make at this stage. We want to focus on students’ ability to hear and manipulate sounds (all done orally only – no print), before they focus on the letter(s) representation of these sounds.
The skill of segmenting onset-rimes is more difficult than that of blending onset-rimes. Activities listed for both segmenting and blending onset-rimes should only be used once students get to this skill of segmenting onset-rimes (and not while still working on blending onset-rimes).
