The goal of the present work is to show the method for teaching the process of solving problems in primary school. The program created on such purpose, consider logical structure of the process of solution and the content of orientation. Participants of the study were regular pupils of private primary school from the city of Puebla, Mexico. The children were tested before and after participation in the program. Qualitative assessment included the tasks for logical relations and problems solution. The program was applied during 30 sessions in classroom. The teaching process was modeled asjoined activity between teachers and pupils. The results showed that the program wasuseful for positive development of mathematical and logical thinking. After participation in the program, the pupils could solve the problems and relate mathematics data to the verbal text of the problems, which had not been observed during the initial assessment. As conclusions, we argue for the necessity to create exact and specific guided orientation to construct mathematics sessions in classrooms in primary school. At the level of modern development of historical and cultural approach, the concept of the zone of proximal development might be related to orientation as essential part of intellectual activity
