This development is held to occur in the fixed sequence of syllables, then onsets and rimes, and finally, phonemes.
It is worthy of note that the above-mentioned consistency calculations are based on spelling body - rime correspondences and not grapheme - phoneme correspondences.
Accordingly, we provided our children with a relatively brief period of literacy tuition at the large unit (onset - rime) level.
