Abstract
The aim of this article is to define the concept of the model for the subject of Mathematics and its importance in the teaching and learning process. First of all, reference is made to the mathematical representational models used to teach fractions (area models, set models, length or number line models). Then, special reference is made to the representational model of fraction tiles, also called fraction strips, through specific teaching examples. The examples are given highlight the added value of fraction tiles to the understanding of basic and complex mathematical concepts for fractions.
