This research shows the knowledge transfers between people of different ages, through meaningful learning processes of concepts in family and socio-educational contexts, which influence children's socialization. The fieldwork was developed using the survey applied to relatives in three localities of the Extremadura region called Sierra Suroeste. The questionnaire focus on the teaching of concepts related to norms and life skills, in addition to the learning relationships between people of three generations within home. The object of study is the verification of knowledge acquired by children of adult family members involved in their socialization, paying attention to grandparents. Likewise, the participant observation was applied in the implementation of intergenerational program at local level, evidencing the transmission of concepts between people of different ages without family relationship. Thus, it was possible to verify the results of this teaching experience, also attending to aspects related to the promotion of autonomy and active ageing. The data emphasize that the main concepts that these minors learn from their adult would be included in the category of "Ethics and morals", "Experiences", "Environmental Education" and "Sports"; while children learn more from their parents, followed by their grandparents, and finally from their siblings.
