Children who go to a playground choose how they use it, for as long as they are there. Often, the organization and choice of structures and equipment follow ill-defined criteria. Also, many decisions are based on beliefs which have not been verified. For example, it is difficult to say whether children prefer going on the slide because the slide is a rewarding activity for them or because the slide is an activity encountered only a few times. As it happens, all parks are equipped with slides but no child has ever said what they think of them and no parent has ever questioned what good they do. It is different in the PrimoSport 0246 playground, where both the spatial organization and the choice of equipment and apparatus are directed towards the motor development of the child. Although unique, this playground sets down some rules that parents may follow to take advantage of locally available facilities.
