In this study, it is aimed to examine the mathematical modelling competencies of pre-service primary school teachers’ in the process of solving the “Time at School” problem. Case study, one of the qualitative research methods, was determined as the design of the research. Thirty-four (34) third-year pre-service primary school teachers’ who are studying in the third year of the primary school teachers’ program in the 2020-2021 fall semester of a state university in the Mediterranean region constitute the participants of the research. The modelling problem named Time at School was used to reveal the modelling competencies of pre-service primary school teachers’ in the process of creating a mathematical model. Written solution process papers of pre-service primary school teachers’ were analysed by descriptive analysis method. As a result of the research, it has been revealed that they are inadequate especially in the steps of the modelling process, understanding the problem, selecting the variables and establishing assumptions, interpreting the solutions and validating the model. It has been observed that pre-service teachers mostly tend to solve the problem directly. In order to overcome these difficulties, it can be suggested to create classroom environments where pre-service teachers can work and gain experience with mathematical modelling problems and model building activities.
