This book practices the student in three letter words containing the short vowel sound of the letter "a." These are not simply lists of words - each book tells a story in complete sentences or phrases but does not progress beyond the short "a" parameters. The first page lists all of the words used in this book and the student should practice reading each of these words before beginning to read the book. If he or she can recognize all of the letters of the alphabet and knows the sounds of the consonants, he is set up to begin reading words with vowel sounds, which are typically the most difficult sounds for the emerging reader to master. By the end of Book One, the student will feel comfortable and competent reading any words containing the "at" combination and will be well on his way to learning to read.
