The divisibility rule in the teaching of Mathematics

Abstract

The divisibility criteria in the teaching of Mathematics play an important role in the study of arithmetic in Primary Education, these are used to simplify fractions, to investigate whether a given number is prime or not, among other contents. From the study carried out by different authors where their treatment is exposed in deferent literatures, it can be seen using the concept of numerical congruence, however, the treatment of textbooks that allow students to appropriate this content is not explained in the textbooks, which is the objective of this work. A study of the divisibility relationship in the whole numbers is carried out; where said relationship is defined and exemplified, it is necessary properties are stated or demonstrated to obtain or demonstrate a considerable amount of divisibility criteria, some of these are exemplified and one of its applications to the resolution of exercises with text directed to this end is illustrated. This work was introduced in the corresponding content of the Mathematics I study program with a population of three groups and a sample of group of the Bachelor of Primary Education.
