How the order is built

Three subjects a lesson, never one

▢

Mixed on purpose

Every lesson teaches three new skills from different subjects, so a child is never doing twenty of the same kind of problem in a row. A lesson is twenty questions, or sixteen in the seven jelly kid lessons that open the course.

↑

Nothing before what it needs

Each skill lists what it depends on, and the order is built from those dependencies rather than typed out by hand. New work in a lesson stays inside one year, so a lesson never jumps from grade 1 to grade 4 and back.

↺

Old work comes back

A lesson brings earlier skills back as practice, and never work more than a year below what it is teaching. A skill the child has secured returns on a spacing schedule: one day, then three, seven, fourteen and thirty.

Standards

Every skill names the standard it meets

The Common Core code is on each skill in the grown-ups' skill report, with Virginia's Standards of Learning listed alongside. You can switch the report between reading it by topic and reading it by standard.
