Welcome to Mathnasium of Thornhill

Center Director
Hello. I'm Robyn Steiner, Owner of Mathnasium of Thornhill, your neighbourhood math-only learning centre. We help kids in grades 2-12 understand math by teaching the way that makes sense to them.


When math makes sense, kids leap way ahead – whether they started out far behind or already ahead in math. Our formula for teaching kids math, the Mathnasium Method™ has transformed the way kids learn math for over a decade across 1,000+ centres in the US and Canada:

  • We know how to teach your child math.
    Our specially trained math instructors will teach your child how to understand math in an individual setting – our unique approach enables us to effectively explain math concepts well and lend a helping hand to every student. Our tutors foster a caring, encouraging environment that helps kids thrive and learn!

  • We pinpoint your child’s learning needs, meet them where they are, and take them where they need to go.
    Mathnasium instructors use our unique assessment process to determine (with great accuracy) exactly what each child knows and what they need to learn. Next, we design a customized learning plan for teaching the concepts the student needs to master. It doesn’t stop there – our encouraging instructors continually check progress along the way to make sure kids truly understand and retain the concepts we’ve taught. The results are transformative – kids will see measurable changes in attitude, confidence, and school progress.

  • We will help your child overcome homework frustration.
    Our instructors will also set aside time to provide homework help. We help kids understand the homework assignment so they feel better prepared to complete the work at home – underscoring their understanding of concepts and transforming homework frustration into a welcome challenge.

About Our Centre


How COVID19 Has Impacted Our Program:

First and foremost, we are still open! We never closed, actually.

In March 2020, we transitioned all instruction online (maybe you've heard about Mathnasium@home live one-on-one instruction).

On June 22nd, after careful preparation and implementation of new safety protocols (masks, limiting # of students, plexiglass screens, disinfecting between each session and more!), we resumed in-center instruction. We have also kept Mathnasium@home available for those who wished to continue from home.

Now with the latest Ontario restrictions/saty at home protocols, we have once again suspended in-person programs but remain open ONLINE! 

Just like you, we're doing our best to navigate through the challenges brought on by COVID19. And, as long as students need math support, we'll find a way to deliver!

Great instructors delivering great teaching. Big personalities, caring hearts, attentive minds. Making math learning fun and making math make sense. The Mathnasium Method - that's our center! 

Customized Learning Plan... Expert and Fun-Loving Instructors... Proven Results. 



Also available in your area, real-time face-to-face instruction over an internet connection.
