An AI course that shows the arithmetic
Program 01, new. Thirty-three lessons, beginner to advanced.
Thirty-three lessons, beginner to advanced. Most writing about artificial intelligence either flatters the reader or drowns them. This one teaches the mechanism: the formula, the worked arithmetic, and the measured number from the paper that reported it.

Materials a teacher can use on Monday
Program 02. K–12 chemistry.
Most classroom material about science is written either for specialists or for nobody in particular. It assumes equipment a school may not have, background a student may not have, or preparation time a teacher certainly does not have.
We start from those constraints. Every worksheet prints in black and white, works without a device, and can be taught by someone who is not a subject specialist. Each packet names its standards, its running time, and what it assumes students already know.

High school chemistry, four full years
Available now, version 1.0.0. One hundred and forty-four weeks across Grades 9 to 12.
One hundred and forty-four weeks of classroom-ready chemistry across Grades 9 to 12. Every week ships a student worksheet, a competition problem set, and a curiosity reading. Grades 9 and 10 released 26 July 2026, Grades 11 and 12 released 28 July 2026, both at version 1.0.0.

Three pathways through every topic
What each week contains.
Competition corner
Harder problems for students who want them, written in the style of olympiad and contest questions but tied to the same week's topic.
Curiosity reading
A short read that puts the week's chemistry somewhere real. No prerequisites, no problem set, meant for students who ask why this matters.

Built to a standard, not just written
Every packet is checked before release.
- 1Standards mappedEvery packet carries its NGSS standards, science practices, and crosscutting concepts in machine-readable metadata.
- 2Accessibility consideredText-only alternatives for visuals, sentence frames, prefilled data tables, and printed dataset alternatives where a lab is not possible.
- 3Audited before releaseNumeric, conceptual, safety, accessibility, and render audits, with checksums recorded for every file in the release.
