In the context of the interdisciplinary unit "How we organize ourselves - Our Neighborhood", we had the pleasure of welcoming to our School the Deputy Mayor of Maroussi, Mr. Yannis Ioannidis, Head of Environment and Quality of Life, who informed Grade 2 students about the actions that a Municipality takes to meet the needs of its residents. He presented the e-park (e-πάρκο) of the Municipality of Maroussi, giving students the opportunity to think about the district in a more sustainable way. We thank him warmly for his detailed and meaningful presence.
