The speech teacher offered to lend me this book after I kept asking how to help my students who were having difficulty making the appropriate sounds. I was trying to figure out on my own how to tell the children to form the various letter sounds. Also, I was having the same dificulty teaching English to Spanish speaking students. This book is just what I needed! I believe every pre-K, kindergarten, and possibly first grade teacher should have access to this book! I don't know how I have taught letter sounds so long without it! It is very easy to understand, concise, and gives many practice exercises.
