Children learn about out world experientially. To connect the brain to the body, it's important to include sensory activities in a child's life to enhance their cognitive development process. Additionally, many classrooms are offering kids multi-level work environments, including floor, desk-height, and standing. This versatile sand and water table will provide the cognitive/sensory experiences kids need as well as a standing workspace when the included lids are in place.
