A few years ago a teacher in my school brought in a curriculum they’d bought online called “All Things Algebra,” created by Gina Wilson. It quickly spread from teacher to teacher. I considered it a niche product, just another thing being sold on Teachers Pay Teachers. Then I was talking to someone at a different school—their colleagues used it too.
It took me a while to realize just how popular these materials were—or how popular they must be, given how often I hear about them. And yet when people talk about the direction that American math teaching is going, Gina Wilson’s name never comes up. She must be the most influential person in math education that nobody knows anything about.

Because it comes from the bottom up, it’s hard to measure Wilson’s influence. Even now, I’m doubting myself—have I overstated the case? There are numbers, though: on Teachers Pay Teachers, she has over 167,000 happy customers.
We don’t talk about Teachers Pay Teachers much anymore, do we? In its heyday in the early-2010s it was the paywalled, cutesy outpost of a freewheeling ecosystem of teacher blogs. Natasha Singer covered it in 2015 for the NYTimes:
As some on the site develop sizable and devoted audiences, TeachersPayTeachers.com is fostering the growth of a hybrid profession: teacher-entrepreneur. The phenomenon has even spawned its own neologism: teacherpreneur.
“Teacherpreneur”—that’s quite a word.
While it’s tricky to figure out how widely Wilson’s curriculum has spread, we can get a bit of a hint from survey results. American Instructional Resources Surveys is a carefully designed survey performed by researchers at RAND that tries to shed light on what resources teachers are using to teach math, ELA, and science. They ask about textbooks and curricula, but also about supplementary materials.
In the most recent results, a full 43% of respondents said they use resources from Teachers Pay Teachers. Those aren’t all using Gina Wilson’s materials, but a lot, maybe most of them are.
Who is Gina Wilson? There is remarkably little public information about her. There is a blogpost from 2013 and a brief interview from 2014. She grew up outside of Buffalo, NY and is a huge Bills fan. In 2006 she graduated college, followed her boyfriend to Virginia Beach, and began teaching Grade 8 mathematics at Great Neck Middle School.
Like so many of us, Gina didn’t like the textbook she was assigned and began searching for materials. She was an avid Pinterester, collecting the free materials that others shared online. At some point, she began making her own sheets and posting them on Teachers Pay Teachers, where she found a following.
What happened next isn’t clear. But now, “All Things Algebra” is a full-fledged curriculum company. It offers full curricula from Grades 7 through Precalculus. How many people work for this company? I don’t know. Based on the pictures Wilson has posted on Instagram, she seems to write these materials entirely on her own, scanning textbooks to find and modify questions for her own sheets. Licenses for her course materials cost several hundred dollars.
Wilson is no longer listed as an employee of Great Neck Middle School. Doing a bit of quick math—hundreds of thousands of customers, hundreds of dollars per course—she must be f***ing rich. I assume she, uhh, is no longer hanging out with 8th Graders? If she is, respect.
What can we say about the quality of Wilson’s materials? Whatever—that’s actually the wrong question, because it doesn’t matter. What’s more interesting is why they’re so popular, and that’s clear to any teacher who’s seen them: they are ready to print and use, with answer keys and plenty of white space after each question.

PLENTY of white space. Oh my god. The hours I’ve lost to white space. There is currently a nationwide effort to get teachers to actually use vetted curricula—“high-quality instructional materials”—and I swear that if people were actually serious about this all they’d have to do would be to ADD WHITE SPACE to these things and make them READY TO PRINT. It doesn’t matter how good your textbook is if it’s annoying to use. The powers that be just don’t get this, but you know who does? Gina Wilson.
There are other things that Gina Wilson understands. Her curricular materials are simple and straightforward, with common structures and routines. The answer keys are important to many teachers. (Not me, but I’m a mess, figuring out answers in realtime.) When there are variations on a typical lesson—activities like “Madlibs” or “Relay Races”—they don’t ask kids to use different mathematics but vary the surface-level activity. I don’t love this personally, because I’m boring and scared of cuteness, but I get that most teachers like these twists on the daily grind.
Last summer, Sarah Schwartz wrote for Education Week about the RAND survey. “Regardless of state or district requirements,” she wrote, “teachers mix and match the lessons and resources they use in their classrooms.” But this reporting doesn’t dig into the actual nature of these supplemental resources, their qualities, or the people who make them. No reporting does, as far as I can tell.
The biggest mistake people make in following education is assuming that classrooms reflect the official requirements. People—even people who should know better—read position papers and state mandates and say things like, “New Jersey is moving in the wrong direction!” or “Finally we’re seeing some changes in Suffolk County.”
If there is anything to understand about education, it’s this: learning happens in classrooms with teachers and little oversight, except from overstretched administrators who, often despite their best efforts, cannot keep track of everything going on in their schools.
43%—that’s a very significant number. That’s a lot of space. It’s the space between curriculum and the classroom. It’s where ed school professors lose their influence, where consultants can’t reach, where state initiatives fizzle away into nothing.
American education will either live with this space, learn to engineer around it, or try to destroy it. I wouldn’t be shocked if, some years from now, the latest technology is used to automate oversight—maybe the next gen textbook will be watching the teacher. But until then, or maybe until that fails, this space will exist—right now it belongs to people like Gina Wilson, and without making much of a fuss, she’s dominating it.
