Before I step into the classroom, I hear children's voices and feel the energy these five- and six-year-olds radiate. Once inside, I see bins of materials strewn about—a scene of organized chaos. The bins are full of toys, blocks, interactive cards, game pieces and other materials meant to develop the children's fine motor skills and enhance their engagement with words and numbers. Some children cluster in pairs or threes, while others work on their own to solve puzzles, sequence symbols and explore.
