This is one of a series of curriculum guides designed to assist bilingual teachers to provide a coordinated program of studies for students in the Connecticut Migratory Children's Program and for any other students whose native language is Spanish. It is felt that an effort should be made to discover the skill level at which a child is functioning, to choose materials from curriculum guides at that skill level, and to move to more difficult materials when the child is ready. Skills are suggested at given grade levels to provide a logical sequence of skill development. The overall focus of the curriculum guides in the series is on Puerto Rican history and culture. The present guide is designed to aid teachers of preschool children. It is divided into three units: (1) Sensory Education Curriculum; (2) Psychomotor Education Curriculum; and (3) Language and Number Readiness Curriculum. Each unit states goals and concepts and suggests activities. The guide is illustrated with black-and-white drawings of the materials to be made. (CFM)
