The Sand Gravel Pit is an immensely attractive sand play unit that will absorbe children in play for hours and hours. The crane is worked by pulling the chain. The sand bucket will go up or down or all around, but it will stay put when the chain is let go of. This, apart from providing fascinating sand play, is a great training of children's logical thinking skills. The negotiation and cooperation to get sand to and from the funnel via the buckets or sand scoops is great for older children and develops social-emotional skills. In the house, multiple tactile elements can be moved to entertain children who wait for the sand crane. The sand funnel here supports children's understanding of object permanence: that things can still exist when out of sight. The platform is open and can be accessed in multiple ways, allowing for all users to play. And on the side, a somersault bar takes care of any surplus energy needed to be burnt.
