Based on the premise that the best teachers are those who have a firm understanding of the developmental needs of children and plan learning experiences to meet these needs, this resource guide was designed to provide prekindergarten teachers with a collection of classroom ideas and activities that serve as examples of how educators can facilitate children's development and skills. The guide begins with discussions regarding how four-year-olds learn, suggestions for managing the classroom, and tips for noting children's progress. The activities are grouped by skill area: (1) language and literacy (oral language, written language, listening, reading, training materials for teachers); (2) math concepts (number, classification, sequencing/ordering, spatial, time); (3) science; (4) social studies; (5) social and personal competence; and (6) creative expression (art, music, movement, training materials for teachers). Each lesson plan follows the same format: (1) skill focused on in the activity; (2) suggested materials; (3) teacher input (key concepts, ideas, and interactions to focus and facilitate the learning process); (4) procedures; (5) independent learning center suggestions; and (6) extension ideas for additional activities. The guide concludes with a resources section containing a book list, interactive stories, songs, rhymes, and fingerplays. (KB)
