Common Phonemic Pitfall to Watch For:
Many early readers attempt to place each letter into its own box (e.g. putting 's' and 'h' in separate boxes for shed). Remind students that an Elkonin box represents a single sound, not an individual letter.
Teacher Prompt: "Say the word slowly. How many mouth moves do you feel? When you say /ʃ/, your lips make one move together, so 's' and 'h' buddy up inside one box!"
