What You Need to Know About Mathplayground Con
The short version is that Mathplayground Con is the annual gathering for people who build, teach with, or create content for the MathPlayground platform. It isn't a massive industry conference. It's a smaller, niche event that draws math educators, homeschool parents, web developers who maintain custom math modules, and a few content creators who publish games and worksheets on the site. If you're looking for keynote speakers from major edtech companies, you won't find them there. You find people who actually use the platform day to day and want to figure out how to make it work better for their students. Most of the schedule is workshop blocks and hands-on sessions. People bring laptops. They share screens. The presenters go through specific mechanics of the platform — how to set up timed practice sets, how to use the custom worksheet builder, how to embed certain games into a learning management system. There are Q&A periods, but they're not polished. They look more like people in a chat room raising their hands and asking the same question three different ways because someone didn't explain it clearly the first time. I went last year because I was trying to get our after-school program to use the platform's progress tracking properly. The main issue I had was that the student progress reports don't export cleanly into CSV. The interface shows the data but the export button produces a malformed file. I asked about it during a session and the developer on stage admitted they'd been meaning to fix it for six months. The workaround I ended up using was to take screenshots of the report pages and run them through a spreadsheet OCR add-on, which isn't ideal but got me what I needed. It's the kind of thing you deal with when the tool is free and community-maintained.
The sessions tend to be informal. There's no badge system, no networking mixer with catered food. People sit in rows of folding chairs in a community room or a school library. Some sessions have twenty people. Others have four. The attendance varies wildly depending on the topic. Sessions about game creation and custom worksheet building draw the most people. Sessions about API integration are usually sparse because the API documentation is minimal and most people who try it give up within an hour.
Who should consider attending
If you're a teacher who uses MathPlayground in a classroom and you want to learn advanced features, it's worth the time. The platform has a lot of hidden functionality that doesn't show up in the help pages. People at the convention demonstrate things like bulk student import, conditional game unlocking based on quiz scores, and how to create custom math operations that aren't in the default library. That kind of information doesn't exist anywhere else in writing form. If you're a developer trying to integrate MathPlayground content into a larger system, it's probably not worth your time unless you're willing to deal with incomplete documentation. The event doesn't provide API access keys or technical support during sessions. You'll get hand-wavy explanations and someone pointing you toward a GitHub repo that hasn't been updated since 2022. I spent forty-five minutes in one session trying to get a webhook working and the presenter essentially said they didn't know either and moved on to the next topic.

What to expect practically
Registration is cheap, sometimes free. There's no travel stipend or hotel block. People usually attend because they drive locally or they're already in the area for another reason. The event runs for one or two days depending on the year. Sessions are forty-five minutes long with a fifteen-minute break between them. The break periods are where the actual useful information gets shared. People swap workarounds, compare notes on bug fixes, and trade custom game files they've built. That informal trading is often more valuable than the structured sessions. Bring a laptop with the latest browser. Bring your own login credentials for the platform. Don't expect printed materials. Everything is shared digitally after the event through a Google Drive folder that someone manages volunteer-style. The folder is poorly organized. You'll spend more time searching for files than you will using them. I downloaded twelve resources last time and only found three that were actually relevant to what I was working on. The rest were outdated versions of features that had already changed.
Limitations and when to skip it
The event has real limitations. The content is uneven. Some sessions are thorough and well-prepared. Others are people reading off slides they made the night before. There's no quality control. There's no peer review of presentations. The organizers don't screen speakers. If someone shows up and says they know how to use a feature, they get fifteen minutes on the mic. That means you'll sit through some mediocre sessions. Budget your time accordingly. Skip the introductory stuff. Everyone already knows what a fraction is. Go straight to the advanced usage sessions. Also keep in mind that the platform itself has constraints. MathPlayground is designed for elementary and middle school math. If you're working with high school or college-level content, you'll find very little that applies. The convention reflects that limitation. Most of the discussions revolve around basic arithmetic, pre-algebra, and introductory geometry. Anything beyond that gets a brief mention and a shrug. If your work involves advanced math, you're better off looking at other communities like the National Council of Teachers of Mathematics regional meetings or online forums dedicated to specific platforms like Desmos or GeoGebra, which have more mature ecosystems for higher-level content. The one thing I'd recommend doing before you attend is read through the recent session recordings if they're posted anywhere. They sometimes upload videos to a private YouTube channel. Watch two or three of them. That'll tell you whether the current year's content is worth your time. Last year's recordings were mostly beginner material. The people who wanted advanced content were frustrated. I'm not sure if this year has improved on that front. The organizers haven't posted any announcements about a curriculum change.
