Learning can be one of our lives' most fulfilling experiences. Or it can be downright dreadful. No matter where or who they are, students deserve a high quality learning program. They deserve to be engaged and inspired, to laugh along with goofy class jokes, and to feel validated because they have the same question as someone else in room.

This must be our mission, and nothing less:

1.) to offer students a gratifying math experience

2.) one that teaches them everything they need to know, at a high level

3.) one that leaves them feeling good about the subject, and themselves, afterwards

Indeed, students need to learn math now, for their current coursework. But the stakes of this moment extend far after their math courses are behind them. Students carry with them both positive and negative memories of learning... for the rest of their lives. Decades from now, they shouldn't be saying, "UGH, I'm just no good at math." They could be saying, "You know I really enjoy math; it's all kinda like a puzzle."

It's no secret that their relationship with math now impacts the rest of their lives. Their career choices, self-confidence, and even just feeling comfortable while talking numbers, or while handling their finances.

Some people... well, lots of people in fact, immediately associate math learning with negative emotions. And no matter how much a student, parent, or teacher valiantly grits their teeth and tries to get through it, we all know the truth. The truth is that no one can learn at their best if their mind and emotions are locked in a negative state.

That's the burning reason behind what I do. If such values resonate with you as well, then so too will these programs. Thank you for considering it.


"I just wanted to say that I LOVE Yay Math! I have hated math since I was in 7th grade, and may have called it 'the death of all things good' (Not being dramatic at all, haha). But now that I'm using Yay Math, I LOVE math! I don't get stressed out any more, and for once I'm actually understanding the concepts!

So, thank you for helping me see that I can conquer, and enjoy, math lessons!

And here is a joke that I drew on my Geometry test:

STOP in the name of the Law... of Syllogism! If you don't stop, you will be arrested. If you are arrested, I will lock you up. If you don't stop, I will lock you up.

Thanks, again, for making math an enjoyable experience instead of drudgery."

Harvard University Provost StatementA statement from the provost of Harvard University, commenting on comparisons between online learning and in person learning:

"Rather than seeking to approximate the campus experience online, we can focus our efforts on creating the best possible remote education experience. A successful shift of this magnitude will require tremendous creativity and dedication."

Robert Ahdoot
Robert Ahdoot

Robert Ahdoot began his teaching journey more than a decade ago as a classroom math teacher. Throughout that time, his personal mission was to explore every specific way to reach his students. He saw firsthand how learning ignited when he connected to them as people. When in such an elevated space, any prior feelings of shutdown they had experienced vanished. One mental note led to several, which led to a living and growing teacher playbook. Through years of dedication and focus on student connection, his classes became fun, lively, and positive beacons of learning for both him and his students.

Yet within so elevated a space, he and his students felt a restlessness. It was the dawn of the video era, and they knew that what they were stumbling upon something could truly benefit others, if they could only experience it themselves. So out came an impromptu camcorder perched atop a precarious stack of books, and the Yay Math movement was born.

YayMath.org is a free online collection of math video lessons, filmed LIVE in Robert's classroom, featuring authentic student interaction, that's both fun and emotionally connective. It has given life to now iconic, full costume math characters, like the "MathemaGyptian" and "MathemaChicken." Since its inception, Yay Math videos are viewed at a staggering 2 million minutes per month.

Yay Math's online proliferation has provided Robert the opportunity to give multiple TEDx talks on conquering math anxiety, speak at schools about how to permanently achieve inspired learning, create comprehensive online courses for teachers and homeschool families to use, and pen his debut book, One-on-One 101: The Art of Inspired and Effective Individual Instruction. It's the complete guide to connecting to kids, and it has been adopted by multiple school administrations as a blueprint for cultivating transcendent student-teacher learning relationships.

Robert and his family recently returned from a 6-month trip through much of the world. He now lives with his wife and two daughters in Oregon.

Yay Math's promises.

  • You don't need a textbook. The curriculum is fully self-contained.
  • The program is complete, covering a full year's worth of Geometry materials.
  • It's easy and instant to implement. Access can begin minutes from now.
  • The interface is mobile friendly, across all devices, and all browsers.
  • All answer keys are provided, by Robert's hand, written out step-by-step, using intuitive coloring, with a human and sometimes light-hearted touch.
  • Yay Math is the first-of-its kind throughout in the world, because its math lessons are filmed in front of a live classroom, with real student interaction. So when you watch, you feel like you're right in that room, sharing in the class's fun vibe. For example, meet the "Mathema-CHICKEN"...

Even chickens need love?

  • You'll get your time back. You no longer need to painstakingly find/create content, sift through the internet ocean, or constantly vet sources. All the work is already done for you, at an exemplary level.
  • Any negative relationship towards math will be healed. Ever heard a student laughing while learning math? It ignites your heart.
  • Best of all, students, parents, and teachers simply LOVE it. It's the way learning ought to be.

Let's just say it: it's time to stop subjecting our students to some of the dreadful learning practices of the past.

No more learning straight from the book, or from notes literally written in Greek, or from emotionless lectures. They only alienate students and stop learning cold. Every student, no matter where/who they are, deserves to have a high-quality math experience. To smile while learning.

"Robert, thank you so much for putting this Geometry Curriculum together. As a homeschooling mom of six, I have made use of your Yay Math videos for years. It was a little hard to admit that my children liked you better than me - but they had so much fun learning from you. Your enthusiasm for learning is definitely contagious. The curriculum has been such a welcomed addition to our home school. It is so easy to use, for both student and teacher! My two sons that are currently using it are learning so much and having a good time doing it. We are hoping for similar programs in other courses. Thanks again for a terrific product!"

Frequently Asked Questions


Who exactly is this for?
The program is designed to fit the needs of anyone with a desire for quality math education.

For teachers, your account gives you immediate access to a treasure trove of materials. The program works as an all-in-one online curriculum that's at your full disposal. You can use it to fuel your day's lessons, showcase videos as needed, and assign both online-based or written practice work. Every lesson plan is entirely done for you, including practice tests, chapter tests, and all hand-written step-by-step answer keys. All materials are also instantly downloadable for you to print, or to post to your school's LMS.

Homeschool families use this platform as a comprehensive, easy-to-use online course. Students jump right in and learn, section by section.

Last but not least, a variety of leaders, independent instructors, independent learners, and special educators use this course for a variety of reasons (e.g. to build necessary skills for a college course, to prep for a standardized test, or for an upcoming career change, or for fresh ideas to bolster their own math teaching practice.)

Reasons for obtaining this program are as unique as people themselves. How about parents who retain access to the course materials, for whenever their children need immediate support in a high school or college class? Or grandparents who use this program to bolster their own understanding, so that they may be active participants in their grandchildren's education? Just spectacular.

Check out this live and interactive pie chart, showcasing exactly who signed up on Yay Math's new Algebra 1 course waiting list. Many different walks of life represented, all in our common pursuit for a comprehensive, relatable, and exemplary math program.

How long do I have access?
Originally, two options were available for purchase: one-year access, and lifetime access.

But then the coronavirus emergency shut down schools, as school officials have openly advised their communities that future closures are very possible. With that situation at hand, I realized that one-year access to this program is not in best service to you. Therefore, for the same price as one year's access, you'll obtain lifetime access to the program.

This way, an expiring account is one thing you won't have to worry about. For less than the cost of a textbook, the program will be permanently yours.
Is the curriculum comprehensive under Core Core?
Yes. 100% of the topics within the Common Core State Standards are covered by this program. However, the topics are not specifically listed under each formalized code. Meaning, when you get to the section on "The Pythagorean Theorem", it'll be called, "The Pythagorean Theorem". It won't be called, "CCSS.MATH.CONTENT.8.G.B.6".
As a teacher, may I pick and choose parts of the program to supplement my own?
Absolutely. This program is clearly categorized by chapter and section, named exactly the way the books name them. So you can grab practice packets here and there, give online quizzes here and there, etc. And of course, you could simply use this program exclusively, as the course covers what is traditionally regarded as a full school year of Geometry.
Is there any formal high school or college credit given for completing the course?
Not directly. But there is a way to obtain course credit. With the shifting educational landscape brought on by the coronavirus, an increasing number of districts and colleges offer accreditation through the submission of a course portfolio.

That way, you may be able to get credit if you submit certain documents they request. For example, they may request sample work with assignment descriptions, course outlines, course codes, and other specifics of this nature. If you'd like, I can happily assist with the professional arrangement of the portfolio documents, at no additional cost to you.

The necessity to receive credit varies for each individual. Either way, at the conclusion of this course, all students receive a personally authenticated certificate of completion. You may choose to pass the certificate along to any educational institution, as you deem appropriate.

Meet Moses. Several weeks ago, his mom and I exchanged messages about whether it’d be possible for Moses to complete Yay Math’s online Geometry course in 5 weeks. People, he did just that. He completed the full course, effectively, in FIVE WEEKS and two days. • This is such a beautiful thing. With the support of his family, Moses had a productive summer of learning from home, while ALSO participating in his other passions, like surfing, golf, and video games. Moses, your story inspires me. It shows how you strive towards a free, fulfilled, and goal-oriented life. That Yay Math plays a role along your journey is such an honor. • May your story now inspire others to walk such a path as well. Respect, young boss. • #math #geometry #distancelearning #learningathome #onlinelearning #yaymath #homeschool #homeschooling #virtuallearning
