In the current context, there are still many difficulties involving teachers and students from the early years of elementary school in the sense of introducing mathematical concepts and definitions that are bases for other mathematical knowledge. Thus, we elaborated a didactic proposal to introduce the square root while the arithmetic content, exploring the notion of perfect squares in the cognitive scope and in cases of squares is not perfect, we resort to the procedure of the Babylonian people, a city in the south-central region of Mesopotamia , current Iraq. Therefore, the epistemological theoretical support adopted was the History of Mathematics, since the pedagogical organization of this material produced is based on the ausubelian theoretical framework. The material was developed in the master's degree in education at the University of Pernambuco-UPE, Campus Mata Norte through a qualitative research-action research with the purpose of serving as a prior organizer to introduce square root in the early years of elementary school.
