The fifth meeting of our Erasmus + project has been held in the 3rd High School of Kilkis. The European partners continue developing the game "Know Europe through its main figures". In this meeting we have learnt about Greek philosophers, specially Aristotle as the cornerstone in the beginning of formal logic and how it affected the country and Europe in general. We have carried out activities within the school such as a presentation by the Greek students on the subject, interactive quiz games and group activities in nature.
