Project: QuaranTiles

If you are like me, your workload hasn’t exactly petered out during these recent weeks of quarantine. Within this new normal, I have found it incredibly beneficial to play. That play is freeform; you could categorize it as aimless, but it is far from mindless. The need to step away from the computer for a few precious moments has allowed me to finish up a couple math projects that have been brewing for a while. The first was the creation of Upscale Pattern Blocks. The second was really an unintended one, born from the influence of Christopher Danielson’s new Truchet Cubes. I affectionately call them QuaranTiles.

Upscale Pattern Blocks

[Updated April 9th, 2020]

First off, I hope you are well. This post represents a portion of my attempt to remain “well enough” in the midst of tremendous uncertainty. Most of my time is spent talking about the teaching and learning of mathematics, something that seems to have ground to a necessary halt in recent days. Given our collective circumstance, the time feels as good as ever to talk about a little project I’ve been working on, and ask for a smidge of help.

The Blocks

Recent access to a laser cutter and a kindergartener got me wondering. I began to play with a few possibilities. One of the fun things that fell out was a set of scaled pattern blocks I’m calling, “Upscale Pattern Blocks”. Essentially, they are pattern blocks scaled in three different sizes. The sizes interacted in some very interesting ways, and after some test cutting and multiple trips to the craft supply store, I ended up with a really fun result.

#FreeScalene

[Update Mar 16, 2020: If you read the following post and feel inspired to spread the geometric love, #FreeScalene products are now available here. Proceeds of the Math Positive store support teachers through professional development book giveaways.]

This past weekend I was invited to Toronto to give the 2019 Margaret Sinclair Memorial Award Lecture at the Fields Math Ed. Forum at the Fields Institute for Research in Mathematical Sciences. While the layers of the organizational hierarchy can be a mouthful, the bottom line is that I was given the great honour of presenting my thoughts on the teaching and learning of mathematics–as they are formulated at this time of writing. I broke the day into three distinct sections: The recipient’s lecture, a poetic provocation about hotdogs and mathematics education, and a gallery walk composed of some of my favourite invitations from my career to date.1

An Improbable Run at the Rosenthal Prize

In early December, I found out that my submission had been selected as the winner of the 2019 Rosenthal Prize for Inspiration and Innovation in Math Teaching. At the time, I had zero reference point to understand what that meant, but have since experienced first hand the hospitality of the international math education community. This post is not a summary of the winning submission; that detailed lesson plan has been posted on the MoMath website. Here, I want to take the time to reflect aloud on how this whole thing happened–a process, I think, might be of value for math teachers. I’ve attempted to distill my take-aways into four categories, but, in actuality, they still exist (for me) as a tangled heap composed of equal parts disbelief, gratitude, and empowerment to pursue the next challenge.

Menu Math Easter Eggs

The best thing about online communities (IMO), is the emergence of artefacts from the collected actions of many people. The online math education community (known as the MTBoS) has seen many of these collections throughout the years, most of which are aimed at supporting imaginative mathematics instruction in grade school. Personally, I have felt the community around Fraction Talks explode right under my nose, and it has been a joy to see how the prompts have sponsored amazing student reasoning. A few months ago, I had another idea for a task structure–that I dubbed #MenuMath–and began to collect examples from engaged math teachers. Since then, the collection has grown and become bilingual thanks to the translation work of Joce Dagenais. I love hearing about student and teacher creations, and you are encouraged to submit menus via my contact page if you feel inspired to do so.

All-But-One Desmos

There is too much to like about Desmos. Really, though. The pace of innovation is gross. I am the first to admit that my sophistication with the platform is lagging behind the possibilities. I have never dabbled in Computation Layer, and I haven’t played with the Geometry. Part of my problem is the core team and the army of fellows are so darn accommodating with any questions.

One of my favourite activities remains the Marbleslides.1 They set a beautiful stage for students to stretch their imagination, and I have not yet met an activity that sponsors a need domain and range in a more organic fashion. I have used them with all secondary grade levels, and they will be a regular part of the weekly work for my undergraduate students in their mathematics methods course this Winter.

Thirteen Days

A huge piece of my identity is invested in being a mathematics teacher.1 This week I began a new and interesting challenge as a university faculty member preparing pre-service elementary and secondary mathematics teachers. This provides me more time to think deeply and openly about the entirety of the mathematics education enterprise, and put some of those ideas into public circulation through speaking and writing opportunities. I am really looking forward to that.

It also means that I am charged with orchestrating the formative experiences with mathematics teaching for about half of my province’s new teachers. That fact is terrifying. I am given just thirteen days in each course with which to shape the impressions, experiences, and ambitions of the future teachers of my province, city, school division, and (quite possibly) my own children. Thirteen days.

Re-Constructing Shapes

For the first time in a decade, I am not reconvening with a high school staff to begin preparations for the school year. (I’m preparing to work with pre-service teachers on a university campus). It feels weird–very weird. It is a day that I look forward to because optimism is a constant across the building. Staff feels fresh, materials are crisp, and possibilities are endless. It sadly belies what’s to come.

Bummer, right?

Thinking Upstream with a Quadratics Menu

Much of what appears in mathematics textbooks is what I like to call, downstream thinking. Downstream thinking usually involves two features that set the stage for learners. First, it provides a context (however doctored or engineered–often referred to as “pseudo-context”). Second, the problem provides a pre-packaged algebraic model that is assumed to have arisen from that context.

A Viral Area Task

Exactly one month ago, fellow Saskatchewan mathematics teacher Ilona Vashchyshyn tweeted about an area task that she used in her class. Long story short, it captured the imagination of Math Ed Twitter like elegant tasks have a tendency of doing.
