Phoneme Segmentation — Elkonin Boxes
Why the CK Digraph Shares One Sound Box
In systematic phonics instruction and explicit phoneme-grapheme mapping, Elkonin sound boxes representphonemes (spoken sounds), not individual letters.
The consonant digraph ck consists of two letters that together represent one phoneme (/k/). When children write duck, they segment three sounds: /d/ ... /ʌ/ ... /k/. When they write pack, they segment three sounds: /p/ ... /æ/ ... /k/. Writing both letters of "ck" together into the third sound box reinforces the vital reading and spelling insight: the two letters form a single sound unit.
