Accomplishment of the objectives in this training module for Child Development Associate (CDA) trainees will aid trainees in advancing children's physical and intellectual competencies, building children's positive self-concepts and individual strengths, and promoting positive functioning of children and adults in group settings. The contents of the module focus first on the teacher's responsibility for mathematics instruction and strategies for teaching mathematics in the preschool. Next, the focus shifts to responsibility and strategies for teaching social science topics and related concepts in the preschool. Focus shifts again to discussions of responsibility and strategies for teaching biological and physical sciences to preschool children. The final two chapters provide resources for the teacher, such as activity and resource unit cards, and guidelines for CDA portfolio development. (Author/RH)
