The objective of this dissertation is to describe the work that we carry through in the elaboration of didactic material that became the teaching of logarithms more significant for the students of high school level. For this we constructed a didactic sequence using resources of mathematical education. To organize our research we use principles of Didactic Engineering. Our sequence also includes exposing lessons, activities with the use of the computer and the calculator. This didactic sequence includes Worksheets elaborated with the concern to make the student had the maximum autonomy as possible to decide them. As well as these activities, exposing lessons, activities with the use of computer and calculator are also part of our sequence. The sequence was applied to 42 students of two classrooms of first grade of high school level, in a cooperative school of the city of Araraquara - SP. For that, 15 lessons of 50 minutes each were used. Most of the activities was developed in pairs. The results were gotten through the analysis of the activities solved by the students and also through the comment and the notes that we made during the application of the sequence. According to these results we consider that our objectives were reached, because the activities were developed successfully and a posteriori analysis showed us that the applied sequence contributed for the learning of the students to occur of significant form.
