Phoneme Segmentation — Elkonin Boxes
Why Digraphs Share One Sound Box
In systematic phonics instruction and explicit phoneme-grapheme mapping, Elkonin sound boxes representphonemes (spoken sounds), not individual letters.
A consonant digraph like ch consists of two graphemes that together represent one phoneme (/tʃ/). When children write chin, they segment three sounds: /tʃ/ ... /ɪ/ ... /n/. When they write bench, they segment four sounds: /b/ ... /ɛ/ ... /n/ ... /tʃ/. Writing both letters of "ch" into the designated sound box reinforces the critical understanding that two letters can represent a single sound unit.
