Gentrification at a Mile High

November 14, 2016

I’m giving another talk this Saturday, November 19 from 2:15-3:05pm at AMATYC‘s annual conference in Denver. I’m excited about attending a conference that’s focused exclusively on math education at the 2-year college level. This talk will be about the gentrification-themed board game that Jared Warner and I created to teach proportional reasoning skills. I will be bringing several copies of the game with me. In the meantime, here are the slides.

Messing Around in GeoGebra

August 16, 2016

This blog has basically become a last-minute repository for all my talks. I’m not happy about that; I’m going to start blogging for real again, but in the meantime, here’s another talk for the repository.

I’m speaking tomorrow (today?) at the Fourth Annual Southern Connecticut GeoGebra Conference. This is an exciting talk for me for a lot of reasons. It’s inspired by a blog post I wrote back in February (back when I still wrote blog posts,) and it will be part of the conference proceedings. Most importantly though, I gave a talk at last year’s conference, which set in motion several exciting collaborations with some really wonderful people. Wow, I cannot believe it’s only been a year! It feels like a decades. In any case, here are my slides. I hope the coming decade year can be every bit as meangingful as the last one.

MAA Metro NYC Talk

April 27, 2016

Jared Warner and I will be giving another talk this Sunday about our gentrification-themed board game. If you’re going to be around at the MAA Metropolitan New York Section Meeting, come find us in room E105 at 3:35pm. As usual, the slides are available below.

Also, many people have asked us where they can get a copy of the game. We’re working on making it available as a free print-and-play through this website. Professionally printed copies will also be available from for a little under $50 a piece. We’re still working out the details though. We’re going to set the price on Game Crafter so that we have a $0 markup, meaning any money made off the game will go to Game Crafter for their services and not Jared or I. The intention is to release the game under a Creative Commons Attribution-NonCommerical license so that others can roll their own mods. For example, I’d love to see alternate boards show up for other U.S. cities, new cards, and other creative spins on the rules. I will post more details here on the blog when we’re ready to start distributing the game.

Innovative Practices in Developmental Mathematics

April 14, 2016

I’m giving a talk tomorrow at LaGuardia Community College’s new Innovative Practices in Developmental Mathematics conference. This is another talk about the gentrification-themed board game that Jared Warner and I created to teach proportional reasoning in Guttman’s City Seminar course. I’m excited to be speaking at LaGuardia, which has a reputation at CUNY for doing cool, new, innovative things…kinda like another Community College I know.

MEC Math Club

March 2, 2016

My colleague Jared Warner and I will be presenting today at the Medgar Evers College Math Club. The talk is about a gentrification-themed board game that we designed to teach proportional reasoning in Guttman’s City Seminar course. This presentation will be similar to our talk from JMM in January, although thankfully will have more time to play the game and unpack some details. Here are the slides for the talk.

JMM 2016

January 9, 2016

One of my New Year’s Resolutions is to update my blog more regularly.

Speaking of which, I’m at the Joint Maths Meetings in Seattle, and I’m giving a talk tomorrow today at 9:40am with my colleague Jared Warner. We’re in the MAA Session on Inquiry-Based Teaching and Learning, IV. We’ll be talking about a gentrification-theme board game we designed to teach proportional reasoning skills in our City Seminar class. Come say hi in Room 619, or take a look at the slides below if you’re interested…

Southern Connecticut GeoGebra Conference

August 24, 2015

I’ll be giving a short presentation tomorrow at the 3rd annual GeoGebra Conference of Southern Connecticut. I’m really looking forward to meeting other folks in the GeoGebra community and hearing what they’ve been doing.

In my talk, I’ll be presenting an activity that I use in my Statistics class at Guttman. It’s based on APOS Theory, and uses a GeoGebra worksheet to help students make sense of the mean and median as objects. As students drag and drop dots on a dotplot, the mean and median dynamically change in response to their manipulations. The slides, handouts, and GeoGebra worksheet can all be found below.

Up & Running Again

August 24, 2015

I just discovered last week that my blog has been down for about a month. As it turns out, Gurpreet Virdi, the CEO and founder of Medialayer, passed away suddenly in June. The company quickly shuttered their doors a few weeks later. My condolences go out to his family and friends.

I’ve moved on to a new hosting company, and will be slowly migrating posts over from the old server. Let me know if you discover some quirks in the process, and welcome back!
