We like to image some aspects of real life with software tools like GEOGEBRA and to teach coding by using SCRATCH. Materials will be drafted student-centred and facilitate also cooperative work among students in one school as well as between the school in our project. We will also foster self-guided learning and creativity among our students . This project can be one step to sharpen Computational Thinking, one of the most important skills for students nowadays. Material from one partner will be tried out and evaluated by others project partners.
