We need to explore the digital world to keep up with our changing world with evolving technology and we need to take our work abroad.We should enrich education in this area and develop the digital competencies of our students and teachers.for these purposes, we aim to develop, disseminate and maintain our Erasmus project on the E Twinning platform. Our project is about coding.This is an Erasmus Plus KA229 project, which involves 5 countries. It is emphasized how important it is to invest in the study of environmental education and civic education especially for the aspect relating to sustainability. Today we are witnessing a lack of a conscience respectful of the environment which is the cause of the climatic upheavals and the serious environmental disasters we are witnessing. Through coding, a valid didactic tool, all the activities of the project will be developed, thus favouring a playful and interdisciplinary approach to the themes chosen with particular reference to science and mathematics.
