Maria Montessori in the book “Education and Peace” wrote: “A great social mission that will ensure the child justice, harmony, and love, remains to be accomplished. And this great task must be work of education, for this is the only way to build a new world and to bring peace”. Today we are thinking of these words spoken, we want to work togheter - teachers and children came from different countries - in order to promote people development, giving voice to their ideas of Peace and make the educational and training proposal an aid to their life. In this project students will create Peace cards and they will send them via post to different schools across Europe. We will work in a multidisciplinary way using a Inquiry-Base Learning methodology. This project should be developed by three partners.
