Guided Practice Script

Now we are going to play like we are trains! Do you know what sound a train makes? Yes! “chooo chooo” Your turn! [1]

Let’s start with making the “h” sound! “h, h, h” (their turn) Good job! [2]

Now pretend like you are going to say “t”. Do you feel that bumpy spot behind your teeth? Move your tongue right behind that bumpy spot. Great! Now round your lips and say “ch” (their turn) Now repeat after me: “chip” (their turn) “cheese” (their turn) “chair” (their turn). [3]

Target Techniques and Considerations

Techniques in the Script

1. Verbal instructions using metaphor
2. Modeling and imitation
3. Phonetic Placement

Common /tʃ/ Sound Errors

• /ʃ/ or /s/ is often substituted for /tʃ/, likely due to difficulty coordinating tongue placement and airflow for the stop & fricative sequence. For example, “share” for “chair”.

Accent or Dialect Variation with /ʃ/

• In Spanish dialects /tʃ/ may sound more like /ʃ/; for example, “chip” → “ship”.
• In British English /tʃ/ can replace the /tj/ sequence; for example, “tuna” → “chuna”.
