Formation of a generalized method of composite pictures assembly.

The article is devoted to description of an experimental study of the problem of a generalized method assembling of composite pictures by preschool children age (based on puzzles (P), composite pictures (CP) and geometric brain-twisters (GBT). A number of conditions have an influence on formation of an assembling method, e.g. type of playing material, insertion sequence of different kind of materials, insertion of materials with/without of used patterns. All these conditions assist or prevent from guidelines selection for an action implementation, formation of a generalized method with formation of which is linked perceptual development.
