The Oasis gravel pit is a hugely attractive play unit that will attract children for hours of construction play. With two sand cranes and sand tables both on ground level an elevated level, the stage is set for cooperative play, stimulating social-emotional skills. The cranes are worked horizontally as well as vertically either by turning the grey plate or pulling the chain. The sand bucket 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 sand table develops social-emotional skills. A lower platform with sand scoop allow small children to enjoy dramatic and explorative play. This stimulates children's language development and cognitive-creative skills as well as their fine motor skills.
