Resumo: This work is part of the problem that questions the process of building major mathematical concepts from Elementary Number Theory for Basic Education. In this context, this study aimed to investigate the conception of divisibility of the K-5 students in School Elementary or through an approach with calculator. The main theoretical references were sought in Resende (2007) and Zazkis and Campbell (2002) regarding the Elementary Theory of Numbers and Sfard (1991) to cognitive processes, Silva et al (1990), Borba and Penteado (2007) and Bianchini and Machado (2010) served as reference to discuss the use of the calculator in the classroom. The qualitative research methodology is based mainly in the Engineering Curriculum. Two sessions with students from the 6th year of public schools in Sao Paulo concluded that among the four concepts focused on the proposed activities: multiple and divisor a natural number, prime numbers and operations division, the students also used a division the calculator and mental arithmetic, half the students showed an operational concept in the process of internalization of the conception of multiple , showed no students meet the mathematical meaning of the term divisor and mostly did not recognize a divisor given representation in prime factors an integer. The calculator was used for all the subjects to calculate and / or validate their responses, being used by some students uncritically, combining alternately with mental arithmetic and algorithmic
