Every puzzle forms a different 12-letter word! Thirty versions are included to outfit your whole class. It could be fun to have students use their word in a sentence to prove they've finished.Students cut out all the squares on their pre-scrambled sheet Students piece together the squares to make a 3 by 4 rectangle so that all touching edges form a matching pair of Standard Form (Ax + Bx + C = 0) and Slope-Intercept Form (y = mx + b) equations.Correct puzzles will form one of the thirty 12-let

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

This gameshow style activity provides great practice for students to recognize the criteria necessitating each trigonometry tool (right and oblique). Students are shown a triangle with some sides and angles given, and they must either: 1) Decide what the most appropriate trig tool would be to determine the unknown (side or angle), or conclude that there is not enough information given to solve it. Or, 2) Decide which trig tool could NOT be used to solve the triangle. (This type of problem

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).
