This article discusses an experience with the project "The children's playgrounds of Mario de Andrade, yesterday and today", undertaken by all the professionals and children of a state primary school in the city of São Paulo. The concern with historical knowledge and the children in the first years of primary school, with their specific qualities, their un-schooled perspective and their inability to predict the school's teaching approach, was the keynote of this study and the challenge faced. A link between history and memory is sought, establishing a relationship between the History of Education, the history of small children being schooled and teacher training.
