The organization of the school day is marked by routine moments: entrance, snack, structured activity, lunch, exit, etc. In these environments, children learn behavioral rules appropriate to different social situations, which have "something ritualistic" from a linguistic point of view; The adult always provides the same input using the same structures and the same vocabulary.

Bruner, in 1983, speaks of the importance of routines and introduces the concept of format, which he defines as "an initially microcosmic interaction structure between an adult and a child, which contains delimited roles that eventually become reversible . Formats are those that parents and children share daily, such as early evolutionary stages, feeding, diaper changing, bathing, and so on. . .
