The Trader, with its inviting enclosed play space, is an opportunity for quieter play. The panels support sand play and the funnels transport sand. This stimulates the understanding of object in the child, the fact that even although you don't see something, like sand in a pipe, that it is still there. The sand scoop panel adds activities for fine motor skills, but also trains logical thinking. When positioned correctly sand can be shifted from one scoop to the next. The fun climbing panel invites shifting things through holes, but also adds a low climb-and-crawl over activity, creating two spaces: the inside and outside. The three sides have different heights, generating varied points for social interaction. The Trader can be simultaneously used by many children, on the inside as well as outside.
