In the context of the PYP Transdisciplinary Theme "Who we are", younger students shape their self-image and learn how they can take care of themselves. On Tuesday, February 4, Elementary School 1 and 2 students gathered at the School Theater to listen to a speech by Ms. Skondra, dentist and mother of one of our students.  Through her lively presentation, they learned a lot about teeth, understood which foods are the worst and the best for their teeth, and promised they would brush them at least twice a day, without forgetting regular visits to the dentist! At the end of the presentation, Ms. Skondra answered students' questions.
