This article presents the second part of a research that aimed to investigate the mediation strategies carried out by children in interaction situations occurred on classroom context. Also, intended to involve teachers by collaboration and intervention. The research, on an ethnographic basis, was developed in two schools of the municipality of Fortaleza: a private one, and another that is philantropical. The proceedings involved observations and tape recordings of the discursive activities of the children in the everyday classroom context while carrying out together the school activities, for further microgenetic analisis. Trying to solve the school activities, children expressed their thoughts, reorganized their actions and searched for new feasible and efficient ways to solve the problems. The particular characteristics of intonations and language expressions were noticed, also as leadership expressions and ways to confirm the enunciative position of each child, which reaffirm the subjective processes occurring in the interactive space of the classroom.
