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 the 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 mathematics 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, selfconfidence, 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 this program. Thank you for considering it.
"The Algebra 2 program was such a good investment for me and I’m so glad I made this purchase. I’m an adult returning to college, taking calculus classes and trying to comprehend the material can be challenging. Trying to make sense of it all while studying, I stumbled upon the Yay Math videos on YouTube. I found that the way Robert describes things made it so much easier for me to understand my college math classes. Ever since I found his videos, I’ve been watching all of them from Algebra to Trigonometry, and they’ve helped me get through my classes. Since his other videos were so helpful, and recognizing that I would benefit from more of a solid foundation in Algebra 2, I bought Robert's curriculum program. It’s so much easier to grasp the concepts now, and so easy to use. I would highly recommend this curriculum to anybody who needs a better understanding this material."

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, OneonOne 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 studentteacher learning relationships.
Robert and his family recently relocated from California to Oregon.
Yay Math's promises.
 You don't need a textbook. The Algebra 2 curriculum is fully selfcontained.
 The program is complete, covering a full year's worth of Algebra 2 course 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 stepbystep, using intuitive coloring, with a human and sometimes lighthearted touch.
 Yay Math is the firstofits 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 "MathemaCHICKEN"...
 You'll get your time back. You no longer need to painstakingly find/create content, sift through the internet ocean, or constantly vet sources. This fully packaged and finished product 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 arduous 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 highquality math experience. To smile while learning.

"Summer of sophomore year of high school, I decided to get ahead in math by taking algebra 2 over the summer. I spent nearly a week trying to find the 'perfect' online course that I wouldn't need a teacher for. I investigated nearly 20 online programs, all of them being faulty in some way. I remembered my homeschool friend who referred to Yay Math as a better Khan Academy. Finding out that he offered an online, selfpaced algebra 2 course, with a 'bundle' option that included algebra 2 and geometry, I knew I had to check it out. I decided to buy the course bundle because I have some siblings that will use it in the future. When I got the course, I was amazed at the amount of effort that was put into it. The answer keys had thorough explanations, and if any confusion was encountered Mr. Ahdoot replied really quickly. I found the course setup overall a unique approach to math. Every day I felt excited and motivated to finish the next lesson. I successfully finished algebra 2 over the summer, and I'm now taking precalculus. While I homeschooled for two years, I never found a course that I could 100% recommend to someone, I can now say that I've found one."

"My daughter Sage is LOVING algebra 2, so much that I had to threaten to “take math away” from her last night, because we were getting ready for dinner and she “just wanted to finish a problem.” :)
Anyway, I was also writing to show you she found a way to export the document of problems into her iPad Mini and work the problems using her Apple Pencil on Good Notes. I wanted to share in case you had not seen anyone do this yet, as an option to printing. I suspect it is also making a difference with her ADD. She has moved to taking all of her notes on the iPad! I have attached screen shots of her work. You probably already know about this, but just in case!
Take care, and thanks again for a great program!"
