A sandbox, often referred to as a playground, is an outdoor area filled with sand where children can play. It provides a safe environment for kids to dig, build, and create using their imagination. Sandboxes are typically enclosed by wooden or plastic borders to keep the sand contained and can vary in size. In addition to promoting creativity, sandboxes help develop fine motor skills as children manipulate the sand with their hands and tools. They also encourage social interaction, as kids often play together, sharing toys and ideas. Overall, a sandbox is a valuable addition to any playground.
