Waterproof and spongy, these versatile foam rocks are perfect for both indoor and outdoor play, encouraging imaginative building, small world play, and hands-on exploration.

Children can use them with the Half Water Channels or Ball Track System to create multiple levels for gravity-fed play with balls, cars, or water. Available in three set sizes (16-piece, 40-piece, and 96-piece), each set includes small, medium, and large rock designs in three natural shades. A Montessori-inspired, safe, and engaging resource, these foam building rocks promote creativity, motor skills, collaborative play, and are ideal for classrooms, playrooms, and outdoor learning environments.
