This article describes a workbook of educational activities recommended for use in elementary and high school classrooms. It is based on theoretical arguments resulting from investigations carried out in the Professional Master's degree program in teaching of mathematics. We aimed to analyze some of the capabilities and limitations of the software GeoGebra in the teaching and learning of trigonometry. We adopted the concepts of the didactic of mathematics related to the use of Information and Communication Technologies with the resources of dynamic geometry software and investigative activities. We briefly describe the structure of the activities workbook, presenting the theories on which it was based and the objectives that guided its elaboration.
