Harness the motivating power of collaboration while maintaining individual accountability! Every students worksheet is different, yet similar in the type of problems asked. When students answer all the math problems, they use their answers to colour-by-number their small section of the larger mosaic! (This bundle was custom-made by request, but the mosaics are available individually as well.) It's simple! 1. Calculate the answers. 2. Colour the squares. 3. Cut out your section. 4. Combin

This task differentiates learning by giving keener students the chance to show their understanding by doing fewer (but more challenging) problems. For grading students work, I usually give "all the points", or "half the points" for a partially correct solution. You could break it into quarters if you need to be more specific :) You can edit the .docx version to suit your specific class needs. This makes a great exam review, even if you don't wish to use it for evaluation purposes! I have upped

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).
