It is a platform which integrates GeoGebra with textual environments to get the functionality of a digital and dynamic mathbook. To support the development we use the theory of semiotic representations and model prototipation. Although we have not yet done experiments with students and teachers, the early tests indicate that the platform can bring various contributions, particularly that concerning the possibilities of interaction and mediation. Specifically speaking, through the platform GGBOOK, the teacher can create activities for students within their own environment, integrat- ing different representations (written, geometric, algebraic) dynamically, without the need for handouts or books to share. In addition, students will develop the activities within the platform, providing access conditions to the teacher to evaluate and give feedbacks.
