This paper has the aim to describe the design, development and application of guiding teaching activities in an area that is usually little explored, the Combinatorics. The study was developed through an intervention that consisted of three activities applied to guiding students in four classes of second grade high school of a state school in São Paulo. The activities were designed with the goal of putting students in a position of action and decision making to facilitate the understanding and the process of knowledge construction and were developed in groups of four or five students. The research classified as naturalist, by the fact that data collection was carried out directly on the site where the problem, is the central issue is to verify whether the teaching of Combinatorics, without the excessive use of formulas, through tutoring activities and use of multiplicative principle, can improve the teaching and understanding of that content. The results were obtained by analyzing the activities addressed by the students who were recorded, by observation, by notes taken by the researchers and also by the evaluation at the end of the research. It was found that the activities were essential for guiding a better performance of students who felt more secure and confident to carry out new activities. These activities represent the final product of this work and it is expected that constitute reference material for teachers who tirelessly seek for new methodologies.
