- Octave-doubling is exponential growth: lesson 8 makes it literal.
- A bubble-tea + ramen price list becomes a system of equations in lesson 2.
- Each lesson rotates a different interest: chess puns for elimination, a basketball arc for parabolas, violin string ratios for logs.

What you get
A full course
Sequenced lessons on your kid’s grade standards, from grade 4 math through calculus.
A placement check
An optional, ungraded quiz before lesson 1. Gaps from earlier grades get a short lesson first; skills they know get skipped.
Lessons they can do alone
About 20 minutes each, in short steps with something to do on every one. A narrator can read it aloud.
Practice until it sticks
Fresh problems until they get three right in a row, then every skill comes back later for review.
A parent dashboard
First-try accuracy for each skill, plus a short email every Sunday.
Homeschool records
Attendance log, progress report, scope and sequence, and transcript, built from their actual work.
How a lesson works
Examples use your kid’s interests. That won’t make math fun on its own, but it gives them something familiar to work with while an idea is new.
Break it down
The concept is split into small pieces, taught one at a time.
Make it theirs
Each piece is shown in something they already know, like a basketball shot for a parabola.
They rebuild it
They put the steps back in order themselves, then practice on fresh problems until they get three right in a row.
For you
What you see as a parent
- Accuracy by skill. See which skills they get right on the first try and which one needs another look.
- Review on a schedule. Every skill comes back later with fresh numbers, sooner if it was shaky.
- A Sunday email. What they finished this week and what’s worth praising.
Strongest in Slope & rate of change. Factoring a trinomial could use a little reinforcement.
