Having recently completed work on a pre-calculus student and teacher resource for Grades 11 and 12, Linh is currently working with a leading math publisher on the development of a brand new national core math series for K-9 schools that will support and address new changes to the Ontario curriculum.

Linh's commitment to education in the STEM fields and her belief in the importance of providing children with a strong foundation of mathematical learning led her to Mathnasium. She is a graduate of the University of Toronto Honours Physics program and has lived in the North York area for close to 20 years.

At Mathnasium, our primary prerequisites for instructors are to be excellent at math, to interact well with children, and to be able to teach exceptionally!  Our instructors include certified math teachers, university graduates of math, physics, aeronautical engineering, computer science, and statistics.  

We find that children are inspired by those who have taken their math knowledge and are looking to apply it in the real world.  Our instructors become role models to our students, showing them that math doesn't have to be intimidating and can be fun.  We have even had younger students express their goal of wanting to be a Mathnasium instructor and help kids learn math when they grow up.  I don't think it is saying too much that Mathnasium instructors change lives, helping students to achieve their full potential, and encouraging them to embrace math instead of giving up on it.
