Central objective: explain how puzzles aid preschool child development by strengthening cognitive, fine-motor, language and problem-solving skills. Supporting elements include contextual trainings, related articles (for example, “The ‘Puzzle Pieces’ of Sleep Stages in Children and How they Fit Together”), curated resources and related job listings to help child care centers apply best practices. Designed for early childhood education and child care centers, this page offers practical guidance and links to deepen staff knowledge and classroom use of puzzles.
