This book presents 350 classroom-tested activities for use with children to create an environment that will stimulate young children's brains. Designed to be used by families, classroom teachers, family childcare providers, or others caring for young children, the book includes information on current brain research and describes interest areas in the child's surroundings. The book's introductory section presents information on brain development in young children and notes the importance of providing activities that stimulate the senses during the early years. Sections on emotional development, social development, physical development, and intellectual development describe the particular developmental domain and suggest activities to facilitate development in that domain. Some activities are meant to be used daily and others are designed to use occasionally. Topics discussed in the intellectual development section include how children learn to think, activities that build children's brains, stories and books, music and the brain, enrichment activities, fine arts, and multiple intelligences. Activities for several classroom areas are presented, including the block area, pretend play area, art area, and the discovery area. The book's final section discusses lessons to be learned from brain research, the importance of providing developmentally appropriate activities, the role of educational delivery systems, classroom atmosphere, problems affecting children, talking with parents, and using brain research results responsibly.
