In this Q&A episode, Rhonda answers a kindergarten teacher's question about incorporating a sound wall with her alphabet. She explains that a word wall is a student's first exposure to using a resource like a dictionary, and it helps children learn letter sounds and patterns. She suggests having an exemplar word for each letter sound combination on the word wall. Rhonda also discusses the use of mirrors to teach letter sounds and the purpose of a sound wall, which helps children see how to hold their mouths when making certain sounds. She emphasizes the importance of teaching the lesson and using mirrors with the children, rather than just putting up a sound wall without instruction. Rhonda concludes by mentioning that there is no research on sound walls, but they have become popular due to the emphasis on teaching phonics.
