Today Minister for Education Richard Bruton launched the World's Largest Lesson in Grange Community College, Donaghmeade in Dublin!
Later that day Our Lady's Bower, Athlone took on the World's Largest Lesson too!
If you would like to learn more about the Sustainable Development Goals, and how we can make the world a better place check out the lesson plan (which focuses on Goal 5, Gender Equality) and certificates for your class.
