Play arcs and play destination messages are passed from older children to younger. Recently, we held a parent training our parent educator called, When Nothing is Everything - the Value of Free Time, and during the discussion period I asked the parents how many of them played in free-ranging groups of mixed ages where the oldest child was 8, 10, or older? Almost all of them raised their hands. When I talk about how play is passed from one child to another, I am talking about older children, 7 through 10 teaching younger children what to play.
