This unit of the Flexible Learning System (FLS) is designed to teach adults how to use toys and games to help children between 3 and 8 years of age learn basic skills and concepts. The text provides an introduction to working with children that is oriented towards new teachers, paraprofessionals, and volunteer staff. Skills emphasized include modeling precise language, contributing to the development of healthy self-concepts, creating conditions for spontaneous learning, helping children develop problem solving skills, and working (responsively) with children. Descriptions are given for a total of 18 toys and 82 games which provide a range of experiences in classifying, ordering, spatial reasoning, patterning, thinking inductively and deductively, solving problems, memorizing, decoding and encoding language, sensing and numerating. Ordered sequences of learning episodes (games) provide specific learning experiences with each of the toys. Unit activities involve working with children, viewing audiovisual materials, making classroom observations, extending and modifying existing games. A basic set of eight toys is accompanied by an introductory film plus a filmstrip and audio cassette for each toy. Other games are illustrated in cartoon strips. All games are described in short easily-read steps.
