This handbook for early childhood educators describes the Sesame Street PEP, an educational enrichment program for 3- to 5-year-olds that makes learning a fun and challenging adventure by using the educational goals of the Sesame Street show, children's books, and developmentally appropriate activities. This program seeks to: (1) stimulate children's natural curiosity; (2) help children learn about the world around them; (3) provide opportunities for children to develop to their full potential; (4) foster a love of reading; (5) boost positive self-esteem; (6) enhance children's language and literacy skills; and (7) develop an appreciation of human diversity. The handbook is divided into seven sections. The introduction explains the program's goals and components. The second section offers tips for implementing the program. The third section discusses developmentally appropriate practices and how Sesame Street PEP meets those criteria. The fourth section offers suggestions for reading with children and includes tips for creating reading spaces and building a library collection. The fifth section contains play and learn activities grouped into the areas of children and their world, human diversity, learning about symbols, and thinking skills. The activities are designed for 4- and 5-year-old children, but tips for adapting them for 3-year-olds are included. This section also includes advice for using the activities and lists of related children's books. The sixth section provides additional resources, and the last section discusses "Today on Sesame Street," the monthly guide to the Sesame Street show. (TJQ)
