Paris and the Eiffel Tower are icons of French, and would certainly enhance you

Experience

I've been a high school math educator since 2008, teaching all grades 9 through 12, and all levels from university and college bound to essentials/workplace to special needs learners. My products and ideas have been gilded by the frontlines of my own classroom experience. I'm always looking for an innovative way to teach the subject I love!

Teaching style

Whenever possible, math should be driven by engaging problems that pull students into the concepts and skills I seek to teach. 'Fruitfully frustrated' is a good place to be :) I enjoy writing and performing math raps (youtube CalfordMath), integrating Geometer's Sketchpad to bring dynamic understanding, gamifying learning (see my product 'Algebra Tile Factris'), and generally pushing creative limits to make math concepts accessible to my students. I am aware of students' math stigmas and horror stories. I try to build on their natural math intuitions, sidestepping their perceived inability to 'do math' because they never won a class game of around-the-world with multiplication flash cards in grade 4.

My own education history

Concurrent BSc (honours mathematics) / BEd (intermediate/senior) from Brock University, 2008 Honour Specialist in Mathematics from Queen's University, 2012 Additional Qualification in Computer Studies, 2023

Additional biographical information

I'm an avid recreational chess player. I enjoy music, skateboarding, longboarding, rapping, programming (see my product 'Algebra Tile Factirs' for a computer game example, or my 'Colouring by...' products for an automated worksheet product), and doing math for fun (total geek).
