Tangram, linguagem e emoção: uma proposta para o ensino de alguns conceitos matemáticos

Abstract

Objects manipulation is one of the first activities children do when they have contact with the outside world by themselves. During this process, both motor abilities and attention skills are being stimulated. While playing, children not only manipulate objects but also develop language abilities to talk to other children or even to themselves. Manipulating mathematical objects results in the creation of configurations that represent figures. Exploring properties implied in figures obtained from this way provides data to discover relationships between these elements. Thus, from activities involving the Tangram, one seeks to establish notions of Plane Geometry, emphasizing the assignment of meanings to drawing (figures) and deduction of areas for these figures. The relationship between thought and language was explored when it comes to graphical objects names. By using their hands as well as language in the relationship with their classmates, children acquire knowledge. It is the dynamic relationship among the neurophysiological, psychological and socio-cultural features that define the final results of the learning activity.
