The Difference in Mathnasium Instructors

Mathnasium instructors are more than just tutors. They are math experts who are passionate about mathematics and teaching children in a way that makes sense. Our instructors are different from typical tutors because they have all been trained to focus on your student's long-term mathematical development, including the development of Number Sense.

In each session our instructors will interact with and engage your child. Their goal is to help students understand their own thinking. Instructors use unique questioning methods to draw the answers from our students rather than use a "lecture" style method often used in schools and by private tutors.

Our rigorous hiring process is designed to ensure we hire only the best. Each candidate is thoroughly tested on their math ability, including all critical elementary and high school topics. All instructors must have teaching, or tutoring experience with children. As part of the interview process, all instructors are expected to complete a trial tutoring session where we observe their teaching style and interaction with kids.

Mathnasium receive training on the proper teaching style and how to teach the Mathnasium curriculum. This training is ongoing and is designed to improve the teaching and communication methods used in our centre.
