This study is aimed at studying the processes of mathematical thinking of primary mathematical teachers. Qualitative research approach is a state study. The study group consists of 7 teachers candidates who study in the second class of the Primary Mathematics Teaching Program of a state university. In the selection of participants, the criteria for being at different levels of academic success and being volunteer were taken into account. As a data collection tool, an open-end problem has been used to encourage teachers to pass through the processes of mathematical thinking. After the problem was solved on paper, each teacher was interviewed with each candidate. The candidates were asked to justify their answers. The answers of the teacher candidates on the problem solving were studied by visual analysis and analyzed according to the mathematical thinking processes expressed by Mason, Burton and Stacey. These processes are the study, generalization, assumption and verification of examples. The study found that in the mathematical thinking processes the teachers candidates had a deficiency. In the course of the study on special situations, all the teaching candidates were limited to the specific situations given in the problem. The majority of the candidates have made the generality to show the sample that the problem contains from the examples they have studied. They made the assumptions in order to reach a judgment from these generalizations, and even some candidates made multiple assumptions at once. However, none of the candidates have failed to confirm the assumptions, which are the last stage of the mathematical thinking process. Some researchers have been given recommendations to the researchers in the field.
