The objective of this text is to bring aspects of the teacher's learning that is involved with the planning of a mathematics class, preparing tasks to be carried out with GeoGebra. The theme of the class is “relative position of lines” and the planning context is that of a group of three mathematics teachers from a full-time school in the state public system of São Paulo, constituted for the development of lesson study, a theme that we investigated in a doctoral research. Group meetings took place weekly for a year and a half. The teachers analyzed the possibilities of exploring the content with the GeoGebra and evidenced learning, such as the understanding that, with the application, students can mobilize knowledge to solve tasks and constitute their own way of understanding mathematical ideas. This understanding leads them to recognize the importance of giving the student the opportunity to carry out investigations, having, in the software, a possibility.
