Sapphire Li


My name is Sapphire Li and I’m very happy to work as a math teacher in ISN. I moved to Italy two years ago from Qingdao, China where I was born and grew up. Before moving here, I spent over ten years teaching math at an American international school of Qingdao in China. I’m experienced in teaching all levels of math from Pre-algebra to AP Calculus BC. My experience gives me a unique ability to teach math in a heterogeneous classroom, to explain complicated concepts in various ways and I never cease learning in my field. I like to study when I am free and this habit enabled me to accomplish my Master of Education in Curriculum and Instructions from Indiana Wesleyan University in 2011. I’m sure I will have a fantastic time with my students as we explore and enjoy the beauty of math together!
