O jogo do telegrama como material didático para a introdução da decomposição de um número em fatores primos

This paper reports a study whose objective was to investigate, through the identification and analysis of the schemes employed by 22 students in the 6th grade of elementary school from a private school sited in Rio de Janeiro, the contributions of a play activity – the game’s telegram – to understand the decomposition of a number in prime factors. This is an analytical study, based on Vergnaud s theoretical ideas. The analysis allowed us to recognize that game situation, as well as its representations, may help students to appropriate some schemes related to the prime factors decomposition.
