The first four books of the Economy spelling series, "Spelling Growth," are reviewed in this paper in terms of content and, to a lesser degree, method. The Economy series is teacher-directed and emphasizes discrimination and identification of sounds. These two skills are clearly useful for spelling, but it is claimed that the series makes considerable and unreasonable demands on both teachers and students. There is considerable review in the Economy series, both within and between books. Review of content of previous books is not indicated as such, but is often presented in conjunction with actual new material. The spelling content of these four books in the Economy series is listed, and it is concluded that the series appears to provide a reasonably good basis for learning the sound-to-spelling correspondences of English, despite inadequacies in the teacher's notes and poor linguistic orientation. ("Spelling Growth" is part of "A Phonetic Approach to Spelling," an eight book series by The Economy Company of Oklahoma City.) (TS)
