The paper discusses the specific elements of clinical work with children in groups: some of these elements are meeting with the chaos, with the primitive emotions and the bodily involvement. Go through and deal with the analytical model these elements is the genesis of any possibility of designing a game that can be shared in the group game. The presence of the adult and his role as the guide, when you work inside the game requires the ability to regress and to immerse themselves in no way to begin to translate thoughts into the language of bodies in motion, noise and excitement, which draw just the beginning narrative fragments. When the conductor resist stopping in K -, can then re-emerge with a building sense that it allows the structuring of a story that the group shares. This path analytic model applied to groups of children can jump-start the evolutionary development.
