Noting that the process of playing with blocks supports the groundwork for learning in every area of a child's growth, this paper discusses specific uses of building blocks in the early childhood curriculum to develop a child's physical, social, emotional, artistic, language, scientific and mathematics growth. The paper outlines the contributions blocks can make to different areas of the curriculum in the areas of physical development, social studies, art, language arts, science, and mathematics, and notes special benefits to a child's self-esteem and social interactions.
