Teaching style
I believe that active engagement is the key to student success. I love incorporating hands-on activities, problem-solving sessions, and collaborative learning into my lessons. Whether students are up and moving, working together, or diving deep into exercises, my goal is to make learning math and physics enjoyable and impactful.
My own education history
I hold a degree in Mathematics from the University of Padua and a specialization in high school teaching for math and physics from the SISS (Specialization for Secondary School Teachers) program.
Additional biographical information
Originally from Italy, I have a husband and two adolescent children. When I’m not teaching or designing resources, I love diving into new stationery—it’s a little obsession of mine! Creating high-quality materials that support both teachers and students is my way of sharing my passion for education with the world.
