The challenge to plan adequate teaching strategies is correlated with understanding the child’s real issue and its timely solution: the more serious the cognitive disability, the later speech develops and remains at a low level in the adult life, generating difficulties in expressing thought and emotion.The examples of interventions we present in this paper come from our attempts to best value the intellectual potential of these children and, consequently, to find solutions for a differentiated adaptation to each child’s needs by planning competence-oriented creative teaching activities.
