2024 has been a transformative year for MA and in reflecting back, two things have stood out to me as being particularly moving. First, the unwavering dedication and unequaled talent of our team. Most of them joined us when we were not much more than a program in a small school district in a corner of California. They willingly and enthusiastically climbed on board and adopted Jason’s vision. We have had the privilege of watching them grow into their own, both personally and professionally, into the powerhouses they are today that produce to exceptional standards. There is nothing more rewarding than that. Second, words cannot express how unexpected and grateful we feel for the community of support that has sprung up around MA. In our wildest dreams, we couldn’t have wished for such an astonishing thing to happen. You (and if you are wondering if I am talking to directly to you, I am) have become what I consider friends, even though we have never met and are half a planet away. It is overwhelmingly humbling to be able to participate in personal journeys of recovery through, of all the unlikely things, the fundamentals of math, overcoming odds, history and circumstances, that I have received many stories via email. It is an honor that I have no words to express. My most sincere wishes to you in 2025: health, peace, happiness and yes, automaticity.

Even a little makes an impact!
My oldest daughter, age 11, rising 7th grader now. 2 months of @_MathAcademy_ last summer, 15-30 minutes/day: 9 points on her Math MAP score (261->270) 🤯 9 months at a "blue ribbon" school, ~10h/wk with the math teacher: 1 point on Math MAP (270->271). 😭 @justinskycak

A kid I tutor went from the 29th percentile in math to the 65th in one semester, from the bottom third of his grade to above average. And he was never bad at math. -->🧵

Shoutout to Zach Nash, my former student and a current @_MathAcademy_ high schooler who just got a math research paper accepted for publication! Funny enough, at the beginning of the 8th grade school year, Zach told me that he would not be doing any more math than was required to pass the class. But by the end of the year, he had absolutely crushed the AP Calculus BC exam, and in the following two years as a Math Academy high school student he learned enough university-level math to be within striking distance of mathematical research. During the summer after 10th grade he worked hard with his teacher Dylan Rupel, a PhD research mathematician, to obtain a research result which has recently been accepted for publication. He will graduate high school this spring and plans to study math at Yale starting in the fall.

Ever since my 7th-grade son started @_MathAcademy_ this past January, I’ve been shouting its praises from the rooftops. Within weeks, his confidence grew and his attitude toward math completely changed. Now we have the data to confirm what I was already seeing at home. After just 5 months in MA, his growth has been remarkable. He went from regressing in traditional public school during 6th grade (44th %ile), to making positive gains at the virtual charter school where I teach (66th %ile), to absolutely knocking it out of the park with MA (99th %ile!). Thank you, Math Academy, for building a program that can change a student’s trajectory. And thank you, @jliemandt and @mackenzieprice for not gatekeeping the secret sauce behind your students’ math success so ALL parents can watch their children succeed!

We love to be a part of student success! 37 point bump! Here's an email I just got: "Hey Sandy, I wanted to send you and Jason a quick note just to say thank you. [My daughter] has done fantastic since starting math Academy. We've spent over $12,000 over the last two years on private tutoring and we even tried tutoring offered by the county school system with very little to nothing to show for it. She only started math Academy in March and we did that after her winter Maps assessment showed a decline from the Fall assessment in percentile (she went from 54th percentile to 50th) . For her end of year maps assessment that she just took, she clocked in at 87th percentile.  I fully attribute this to Math Academy and what you all have built.  It’s been a game changer not only for her understanding but also for her confidence!"

I had a fantastic time discussing with the learning legend @justinskycak from @_MathAcademy_ about learning math in the modern age. we've talked about his quite impressive self-learning journey (3000h of math in high school) all the way to how he hand curated the initial knowledge graph for math academy to make that process more efficient. great lively 3h discussion here are the chapters: 0:00:00 - intro: 0:02:10 - justin background 0:05:45 - 3000h math self study in high school 0:11:45 - what a day looked like for that 3000h stretch 0:16:10 - meta-learning vs pure math learning 0:21:50 - when did you get into cognitive neuro? 0:29:55 - how did the fundamental math helped in your research projects 0:43:10 - what does the math academy learning system looks like 0:47:34 - how did you guys build the 2000 topic knowledge graph 1:01:15 - would LLM be useful as an interface to that knowledge graph for the students? 1:10:46 - how does the FIRe spaced repetition algorithm works? 1:17:34 - does the same knowledge graph structure would work for physics? or other topic?: 1:34:05 - how do you understand the subject vs the curiculum 1:35:50 - is there a connection between studying math and learning a sport? 1:42:00 - do you think in math doing and teaching requires different skills? 1:56:25 - could you get understanding without automaticy? 2:05:35 - do you see any upside of confusion in learning? 2:14:11 - learning math as an adult? 2:19:20 - how to fill the motivation gap after learning the fundamental? 2:24:10 - how should teaching math for kids and adults balance fundamentals and creativity? 2:33:55 - is it ever too late to learn math seriously? 2:46:00 - mastery learning vs ultra learning 2:51:30 - top-down vs bottom-up 2:53:40 - mastery learning for domain without a structured hierarchical structure? 2:56:30 - neurodivergence / adhd for structured math learning? 3:06:20 - amateur mathematician augmented with technology will be able to contribute to research? 3:14:37 - what are you most excited about right now in term of learning enjoy!

Introducing our new middle school pathway!
I’m happy to share that Math Academy’s 6th Grade Math course is now live and open for registration. Math Academy students now have two middle-school pathways to choose from: • 4th → 5th → 6th → 7th → 8th Grade Our grade-by-grade Common Core pathway is best for schools that want full middle-school Common Core alignment and for students who would benefit from the additional content and scaffolding it provides. • 4th → 5th Grade → Prealgebra Our accelerated pathway is fully aligned with 4th and 5th-grade standards, continues to cover many middle-school Common Core standards, and is designed for students who are ready to move more quickly toward High School Algebra. Students can switch between pathways as needed. Our 7th Grade course will launch in a few weeks. Until then, students who complete 6th Grade will be automatically promoted to Prealgebra. Our 8th Grade course will be ready later this spring.

Thank you so much for this recognition! We are so grateful to the families who nominated us!
Mar 24
Most math tools teach to the test. Families kept nominating @_MathAcademy_ because it teaches to the kid. 2026 Eddy Award Winner - Resource of the Year. @justinskycak @exojason shared, "This recognition reinforces our commitment to helping every student achieve their fullest mathematical potential."

I'm just thrilled to hear when kids are succeeding! "Our son has been enjoying his time on Math Academy, making steady progress towards his SAT fundamentals goals. We've also found that he's made progress on another independent, objective metric: the NWEA MAP test score. Last year as an 8th grader he was placed in the low 80th percentile. He just got his 9th grade MAP score and he's now in the 91st percentile. I personally believe the regular daily practice with him enjoying chasing XPs and wanting to stay in the diamond league has a lot to do with it. I love how your program homes in on missing fundamentals and drills those until he is proficient. We've tried many online math learning tools, including Khan Academy, IXL, and Brilliant. I have to say, Math Academy is the best I've seen out there in terms of impact. Thank you!"

For anyone wondering how a third-grader can complete six years' worth of math in a single year. This knowledge graph spans 3,000 math topics, from 4th grade to the university level, providing the perfect basis for mastery learning. Students can go as fast or far as they want! There are no restrictions whatsoever. The only requirement is that they must demonstrate mastery of each topic before moving on to the next. Kids are capable of incredible things when given that kind of freedom and support.
Today feels big. My third grader earned another stripe on his BJJ belt and then casually finished the last lesson of his Calc BC course.  This kid, who just over a year ago claimed he hated math, fell in love with the subject when he started @_MathAcademy_. He became thirsty for more and more math. He has been setting his own goals, and they vastly exceeded anything I would have dared set for him.   He finished 6th through 12th grade math in just over a year.  He hates reviews 😂 and loves new lessons. He doesn't like calculations but loves concepts. He takes math notebooks to restaurants so he can toy with proofs while he waits for his food. And he cannot wait for the MA Abstract Algebra course (@ninja_maths, counting on you!)
