Key Phonics Clarifications & Targeted Intervention
1. Blend Articulation (thr):
Ensure students pronounce /θ/ + /r/ smoothly without inserting a vowel ("thuh-ree"). Mirror mouth moves: tongue tips out, then curls up and back.
2. Two Sounds of 'ow':
Remind students 'ow' can say /aʊ/ (owl, cow) or long /oʊ/ (bowl, snow). This lesson targets ow in bowl (/oʊ/), contrasting with ou in out (/aʊ/).
