In 1996, Gay Su Pinnell and Irene Fountas presented Guided Reading, the most comprehensive guided reading resource ever published. Hailed for its practical, systematic approach, the book showed hundreds of thousands of teachers how to address the needs of the whole classroom as well as individual readers. Now, with the publication of Word Matters, Pinnell and Fountas offer K-3 teachers the same unparalleled support, this time focusing on phonics and spelling instruction. Word Matters presents essential information on designing and implementing a high-quality, systematic literacy program to help children learn about letters, sounds, and words. The central goal is to teach children to become "word solvers": readers who can take words apart while reading for meaning, and writers who can construct words while writing to communicate. Where similar books are narrow in focus, Word Matters presents the theoretical underpinnings and practical wherewithal of word study in three contexts: word study that includes systematically planned and applied experiences focusing on the elements of letters and words writing, including how children use phoneme-grapheme relationships, word patterns, and principles to develop spelling ability reading, including teaching children how to solve words with the use of phonics and visual-analysis skills as they read for meaning. Each topic is supported with a variety of practical tools: reproducible sheets for a word study system and for writing workshop; lists of spelling minilessons; and extensive word lists, including frequently used words, antonyms, synonyms, and more. Armed with these tools-and the tried-and-true wisdom of Gay Su Pinnell and Irene Fountas-teachers can help students develop not just the "essential skills," but also a joyful appreciation of their own literacy.
