“…Examples of flexible use included socializing on play equipment through sitting and chatting and not being active [51,57,67,71,79,80], climbing up swing posts [58,59,65] or play houses [57,67,88], balancing on rolling bars [88], using play equipment to hide [57,59], jumping over sand pits [84], or hanging from play equipment such as basketball baskets [84]. Other children exhausted affordances for play in a diversity of approaches to play equipment, such as sliding-play by sliding on their tummy, backwards, head-first, or climbing a slide [53,65,67]. Additional loose materials such as water, sand or stones on slides [54,71,89] or filling spinning equipment with surface materials [59] were applied to play equipment.…”
