Finally understand every piece of Math 1
A complete, step-by-step California Common Core Math 1 course — built for real high school students who want algebra, geometry, and statistics to actually make sense, not just feel possible on a good day.

I never skip a step, because I know that's usually exactly where confidence is lost — and I'm here to make sure that doesn't happen to you.— Gaia Brux

A note from your teacher
Gaia Brux
Hey — I see you.
Maybe you opened your Math 1 textbook and felt that familiar sinking feeling. Maybe your teacher moved on before you felt ready, and now you're a few topics behind and not sure how to catch up. Or maybe you're not behind at all, but you want to actually understand what you're doing — not just survive the next quiz. Whatever brought you here, I want you to know: this course was made for exactly where you are right now.
Math 1 is a big course. Algebra, graphing, quadratics, geometry, trig, statistics — it can feel like a lot is being thrown at you all at once. What I've built here is a path through all of it that makes sense. Every lesson starts with the why before the how. Slope isn't just "rise over run" — we talk about what it means when a phone plan charges you per gigabyte. Quadratics aren't just an equation to memorize — we look at what happens when a soccer ball leaves your foot and arcs through the air. When math connects to things you can picture, it stops feeling like a foreign language.
I also never skip steps. Not the ones that seem "obvious," not the ones that take a little longer to set up. Because I know from experience that the moment a step gets glossed over is often the exact moment a student decides they just aren't good at math. You are capable of this. Every part of it. You just need someone to walk through it with you at a pace that lets it stick.
Here's what I want for you: by the time you finish this course, I want you to look at a Math 1 problem — any of them — and feel like you know what to do. Not because you memorized a trick, but because you genuinely understand the idea behind it. That's the kind of confidence that carries you into Math 2, into science class, and beyond.
This course is patient, it's complete, and it's in your corner. Come learn with me — let's make Math 1 the class you actually feel good about.
