Making Math by Design — Queen’s College

I’m excited to be visiting Queen’s College on Tuesday to speak to students in QC’s TIME 2000 program. TIME 2000 prepares future teachers by having cohorts of undergraduates study math and education together. The program also puts on a great conference that shares the fun and beauty of math with high school students.

I’ve participated in the conference several times, but on Tuesday I’ll be speaking at the TIME 2000 Spring Seminar series. In Making Math by Design I’ll talk about the decisions that teachers make, and the consequences of those decisions, when we design and implement mathematical tasks for our students. I’m looking forward to doing some math together and having a good conversation about it afterward.

It’s been several years since I’ve visited Queen’s College, and I’m excited to be heading back, especially since this talk was originally scheduled for 2020 and was my first in-person talk cancelled by the pandemic! Let’s hope nothing else happens before Tuesday.

Pitfalls for Parents — MoMath

I’m excited to be joining Steven Strogatz this coming Monday for QED: Pitfalls for Parents, hosted by the National Museum of Mathematics.

In this event, Steve — a renowned mathematician, author, and speaker, as well as the museum’s current mathematician-in-residence — answers questions from the audience about K -12 mathematics. Steve has been inviting classroom teachers along as special guests, and I’m thrilled to be joining him on February 7th at 7 pm.

You can find out more about the event, and register, here.

Why Triangles are Easy and Tetrahedra are Hard — Quanta Magazine

My latest column for Quanta Magazine is a celebration of the Triangle Angle Sum theorem, a favorite result from high school geometry.

Do you think there’s a triangle whose angles measure 41, 76 and 63 degrees?

At first, answering this may seem easy. From geometry class we know that the sum of the measures of the interior angles of a triangle is 180 degrees, and since 41 + 76 + 63 = 180, the answer must be yes.

But there’s more to this question than meets the eye.

From triangles we move to tetrahedra, where a surprisingly simple question about angles wasn’t resolved until 2020. You can read all about it here.

2021 — Year in Review

A return to in-person schooling was the biggest news of 2021. I don’t want to be accused of burying the lede.

It’s been great to be back. It’s also been an interesting challenge trying to weave together what I learned over the past year-and-a-half as a full-time remote teacher with what I was doing in-person before that. Add in new colleagues, redefined priorities for teacher teams, and a brand new course to teach and it’s been a pleasantly busy return to the building.

I’ve also stayed busy with a variety of talks and webinars this past year. As always I ran several workshops for Math for America, like Bringing Modern Math into the Classroom in January and It’s All Linear Algebra in November. This summer I participated in a roundtable discussion at the National Museum of Mathematics on math education. And I was thrilled and honored to run a week of morning math for the Park City Math Institute’s Teacher Leadership Program, satisfying two long-standing professional goals: to participate in PCMI and to finally make sense of complex multiplication!

I continued to write my column for Quanta Magazine, which is on ongoing professional highlight. The year started with the crooked geometry of round trips (an article that was picked up by Wired magazine) and covered everything from hot dogs to goats to tricky job interview questions.

I was proud to keep up my Remote Learning Journal throughout the 2020-21 school year, and was happy to have the opportunity to reflect on the totality of my experience on the MAA’s Math Values blog, where I published “Let’s Remember the Year Everyone Wants to Forget“. I was also able to capture some fun moments in writing this past year, with a short story about an absolutely brilliant student solution to a calculus problem as well as a Seussian poem proof of the irrationality of the square root of 2.

Without question my single biggest professional project this year, writing or otherwise, was getting a manuscript submitted. I knew it would be more work than I expected, and it was. But the process was exciting and eye-opening and worthwhile, and I am thrilled that Barron’s Painless Statistics will be out in June 2022.

It’s been another year full of challenges, changes, and opportunities, and I hope 2022 brings us a healthier balance of all those things.
