This bibliography, pertinent to preschool math materials, contains math materials, contains references which are largely devoted to descriptions of materials and to an explanation of their use. The content of each reference has been described briefly and notation has been made concerning inclusion of plates which would picture the material or even show it in use. Also included in the bibliography are some math curriculum guides which may be of interest to teachers. This bibliography is by no means exhaustive, but it does acquaint the reader with several of the materials from structured math systems which are available, but not generally in use. (Author)
