A map of every skill, and a short path through it

Every subject is a skill map: hundreds of skills from kindergarten to high school, each linked to the skills it builds on. Counting comes before adding; fractions before ratios; ratios before percents.

The placement check asks about the skill that splits the remaining map in half. Get it right and everything beneath it is very likely known; miss it and everything above it is very likely not. Each answer settles a whole chain of skills, so about 20–40 questions cover what a grade-by-grade test would need hundreds for.

A single slip never decides anything. A skill isn't marked as missing until the student misses it again, and a student who keeps answering correctly can keep climbing past their grade. The check starts near your child's grade for the youngest learners, so a kindergartner never opens on a fifth-grade question.

The result is the child's frontier: the skills they're ready to learn next because everything underneath is in place, plus any gaps, earlier skills that are missing and quietly causing trouble.

Grade level is shown as a report, never a gate. A sixth grader who has mastered grade-eight math sees grade-eight work; a sixth grader missing a grade-four fraction idea gets that one idea, not a whole year again.

Each week every subject gets a few practice cards of about 5 questions (4 for the youngest):

• Refresher cards for gaps, oldest and most important first.
• Practice cards for the frontier.
• One stretch card, “one step past your best”, every week.
• Review cards that bring back mastered skills after 1, 2, 4, then 8 weeks, so they stick.

A short weekly check-in confirms what moved and updates the plan. Kids can ask for a skill they're curious about; it shows up once a parent approves it.

Every skill has a short lesson: a few idea cards, each with a plain explanation, a worked example, key words, and what a finished answer looks like. It's one tap from every practice card.

After each practice answer the child sees the big idea behind it, with a step-by-step solution and hints when they miss. The goal is understanding the idea, not memorizing the answer.

Every question is written to a standard, answered blind by a separate checker to make sure the key is right, and read “cold” for clarity at its grade level. Math changes are approved by a person before they go live.
