Math professional learning that shows up in your scores.
We grow teachers as mathematicians first. That is the only sequence that has ever moved student math achievement - and we price ourselves against the result.
You have invested in math.
The scores have not followed.
Districts have likely invested tens of billions of dollars - an estimated $40-70 billion on math PD in the last decade. NAEP scores are declining. This is happening everywhere.
Workshops that never reach Monday
Research finds PD under roughly 14 hours has no measurable effect on student learning. Most PD is one-off.
Yoon et al., IES 2007New materials, same instruction
Districts adopt new curriculum cycle after cycle. The materials change. The classroom does not.
The pattern every leader recognizesCoaching without a mechanism
Support without a clear model for changing how teachers facilitate math discourse produces nothing durable.
The gap no vendor talks aboutIt is not the curriculum.
It is the instruction.
Your kids will not do better
than your teachers can do.
Decades of research converge on one finding: teacher mathematical understanding and facilitation skill are the mechanism. Materials do not teach. Teachers do.
Teacher content knowledge is the single strongest school-level predictor of student math achievement.

How math scores actually move.
This is the only sequence that has ever worked.
This program is built on it — end to end.
From consumers of math to producers of mathematics.
The Consumer
- Rewards memorizing disparate procedures
- Rewards algorithm deployment over understanding
- Treats math as a static pile of skills and facts
- Measures only the answer
- Assumes math must be made interesting for the learner
The Producer
- Contributes to a knowledge-building community
- Thinks critically, works collaboratively, communicates ideas
- Sees math as a network of interconnected ideas
- Values the reasoning process over the answer
- Finds math interesting and relevant of itself
The math that actually moves scores.
Three things separate math that sticks from math that does not. The PD is built to install all three.
Exercises
The core move
A prompt the whole room has to reason through together. No procedure. No shortcut. No back of the book.
8(7) + 5 ______ √9 + 7 · 8
Compare these expressions. Insert >, <, or =. Convince the room.
No procedure to retrieve, no shortcut to hide behind. Teachers reason from what the numbers are - and defend that reasoning to colleagues. Then they learn to facilitate the same discourse with students.

Dialogical
Students argue. Students explain. Students change their minds because a classmate made a better case - not because the teacher said so. Math becomes something you do with other people.
Rooted in first principles
No memorized procedures. Every claim has to trace back to what the numbers actually are. Students who reason from first principles can rebuild the procedure any time. Students who only memorized it are stuck the moment the problem does not match the template.
Reasoning over answers
The room is the judge. A right answer without a defense does not count. A wrong answer well-defended teaches everyone something. Mathematical thinking gets grown out loud, under pressure, in front of peers.

It holds up in middle school, too.
In pilot classrooms, over half of 7th graders reached proficiency against 4% in non-pilot rooms. In 8th grade, pilot classrooms took proficiency from zero to 29% - in a school where no non-pilot 8th grader tested proficient.
School-wide, students in the program made a median of 157% of typical annual growth, with 69% improving their placement level.

Every teacher gave it five stars.
That almost never happens.

Got my staff into the work and language of math.
There is more than one way to do math. The process is more important than the answer.

Sustained by design - not another one-off.
Grow teachers' mathematics
- 18-hour summer immersive before school starts - teachers experience the framework as learners, flexibly scheduled over 2-5 days
- Sustained workshops through the school year - full-day or half-day, a mix of in-person and virtual, each building on the immersive
- Teachers meet regularly as a knowledge-building community, doing real mathematics together between sessions
Students grow faster than a typical year - driven by teachers who teach conceptually and not just procedurally.
Grow leaders you keep
- 6-12 teachers selected as emerging instructional leaders from the Year One cohort
- A second 18-hour immersive focused on designing and facilitating Thought Exercises in their own classrooms
- Weekly virtual coaching with video-based feedback, plus 2-4 in-person observation and planning days
Acceleration compounds - and the instructional expertise stays inside your district.
The impromptu rehearsal room.
A proprietary app that lets teachers practice facilitation with AI students and an AI coach before running the lesson live.
Where facilitation gets grown
Teachers step into a live math discussion with two AI students holding real misconceptions. Not homework. Not video. Impromptu rehearsal with "students".
An expert coach beside you
Every session comes with an in-the-moment coach trained on Kevin Moore's method - his moves, his diagnostic questions, his way of pressing on reasoning.
Unlimited practice, zero risk
Unlimited practice, zero risk to real students. Teachers can try the harder move, misfire, and run it again - no class period spent finding out.
Leaders see the growth happen
Every rehearsal produces data. See which teachers are engaging, which are growing, and who your emerging instructional leaders are.

Priced to say yes to.
per cohort of 20 · teachers, coaches, SPED, admin - you choose the mix
- Includes the full summer immersive and all school-year workshops
- Neighboring schools can share summer immersives - same fidelity, shared logistics
- Year Two instructional-leadership tier priced as an add-on for continuing schools
- Sized to sit inside existing PD and Title II budgets - no board-approval gauntlet
We put our money where our math is.
You decide whether the year was worth it. No other math PD stands behind itself that way.
Compare it to what you're buying now
Sending one teacher to a national conference - flight, hotel, registration, a sub back home - easily runs $2,000-4,000. That buys a binder and a good week. This buys a year that keeps teaching after it ends.
And it compounds
Year Two turns your strongest teachers into in-house facilitators. Every year after, the expertise is on your payroll - not ours.
Questions leaders ask
A Year One partnership is $40,000 for a cohort of 20 - an 18-hour summer immersive before school starts, plus sustained full-day and half-day workshops through the school year, in person and virtual. You choose the cohort mix: teachers, coaches, SPED, administrators. Year Two, which grows 6-12 of those teachers into in-house instructional leaders, is priced as an add-on for continuing schools.
Most math PD trains teachers on materials. This grows teachers as mathematicians. Research finds PD under roughly 14 hours has no measurable effect on student learning, so the program starts at 18 hours and continues across the year. And it targets the actual mechanism: what teachers understand mathematically and how they facilitate discourse.
A prompt the whole room has to reason through together, with no procedure to retrieve and no back of the book. Teachers reason from what the numbers are and defend that reasoning to colleagues - then learn to facilitate the same discourse with their students. It is the core move of the Generative Math Learning Framework.
In a kindergarten pilot, students went from 0% on grade level in the fall to 67% in the spring, against comparison classrooms that moved 17% to 25% - eight times the growth, starting from further behind. At Phillips Middle in Edgecombe County, NC, 54% of 7th graders in pilot classrooms reached proficiency against 4% in non-pilot rooms, and 8th grade went from zero to 29%. School-wide, students made a median of 157% of typical annual growth. All measured on the i-Ready Math Diagnostic.
We return 50% of your investment if you are not satisfied with the work. There are no thresholds to hit and no fine print - you decide whether the year was worth it.
An 18-hour summer immersive before school starts, flexibly scheduled across 2-5 days, then sustained workshops through the school year in full-day or half-day blocks, mixing in-person and virtual. Between sessions, teachers meet as a knowledge-building community and do real mathematics together.
No. This is not a curriculum adoption, and it does not replace your materials. It changes how teachers understand the mathematics in whatever materials you already use, and how they run the conversation in the room.
It is a teacher tool, not a student one. Between workshops, teachers practice facilitating a live math discussion with AI students holding real misconceptions and an AI coach trained on Kevin Moore’s method. Leaders get visibility into who is practicing and who is growing. It is on the partnership technology roadmap and is currently piloting with founding districts.
It is sized to sit inside existing PD and Title II budgets, which is deliberate - most districts can approve it without a board-approval gauntlet. For comparison, sending a single teacher to a national conference typically runs $2,000-4,000 once you count travel, registration, and a substitute.
Yes, and we recommend it. Start with a 45-minute conversation with your leadership team, then book a half-day session for your leaders and math teachers, priced at cost. Most leadership teams describe the half-day as the moment they got convinced - because they do the mathematics themselves.
A small first yes - not a leap.
Start with a 45-minute conversation. Nothing about this partnership asks you to commit before you have seen the mathematics for yourself.
