Pie Chart / Circle Graph - Simple Template
Pie graphs can be tricky to make by hand when the sections aren't easy fractions of the pie. This simple template gives a circle marked off with 100 'tick lines' for easy graphing of percentages of the whole pie. A second template using dots is included too. A dot in the centre of the circle is included too, making it easy to use a ruler and draw lines out to the edge.
It's a .docx (Word) file containing two images. Feel free to copy, paste, modify, distribute, embed...

Metric Measurement Code - Collaboratively Decode the Inspirational Quote
Students measure the zig-zagging line segments on their page to the nearest tenth of a cm (to the nearest mm), and use the code legend to decipher their worksheet's message based on the lengths. See the product preview for an example! Each of the 8 worksheets contributes part of the Francis Chan quote: "Our greatest fear should not be of failure but of succeeding at things in life that don’t really matter." The line segments on the worksheets actually print out to be the real-life size (printe

Imperial Measurement Code - 16th of an Inch, 12 Corny Joke Worksheets!
Students measure the line segments to the nearest 16th of an inch and use the code legend to decipher the punchline to the corny joke on their worksheet. Each of the 12 worksheets is different, so you don't need to worry about students simply copying the answer. The line segments on the worksheets actually print out to be the real-life size (print letter size: 8.5x11 format). Since each page is different, this activity provides individual accountability while allowing students to help each ot

Ice Cream to Algebra Continuum
From my own classroom experience, I would say this is one of the most effective activities I've ever created! I've had students mention after class how easily they followed the progression of problems and that they now understand how to get a linear equation from two points so much better than they thought they ever would. This activity draws on a familiar context of purchasing ice cream, at first, by the scoop without a cone, but gradually working up to cases providing the total cost for two d

Word Fractions - Corny Pun
Students join fractions of words to create a new word. At the end, the new words create a sentence (the corny pun: "Two peanuts walked down a dark alley. One was a salted.") For example: First half of twin + last 1/2 of go: tw + o = two I created this for my grade 9 essentials math class, to review the very basics about what a fraction means, and they were all able to be successful and enjoy the pun at the end!

"The Interview" - linear systems application problem from New York Times article
A humorous mathematical oversight in a New York Times article provides a great 'real life' linear systems application problem!
The problem involves the opening week rental and sales income from Sony's controversial movie 'The Interview'. The article claims that the number of rentals and sales is not known, but only the total profits from both, and the combined number of transactions... honestly, it's like they wrote the article for a math text book :)

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.

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).
