This article presents a model for analysing how probability is treated in Chilean textbooks in
primary education. In order to do this, we have used theoretical tools from the Onto-semiotic.
Approach to Mathematical Knowledge and Instruction which have enabled us to identity
mathematical objects (problematical situations, language and concepts) associated with the study
of probability. These objects are analysed according to the diversity of their meanings, based on
the official Chilean curriculum. The results show that probability is treated mainly from an
intuitive perspective, with frequency and classical meanings then being incl
