Math for the homeschool year

Built by a professor of computer engineering for his own kids, and shaped like a homeschool parent thinks: a placement diagnostic instead of a grade-level guess, a mastery map that shows exactly which skills are solid and which are due, and a parent view across every child.

It is free during the beta - everything, no card - so it costs nothing to run it alongside the curriculum you have already chosen and see whether it earns a place. A full math curriculum for one subject often runs $300 to $800; the one-time Founding Annual Pass ($129) covers every child in the household for the year after the beta ends.

Why it fits a homeschool day

• Placement, not assumption. About 15 questions find each child's actual starting rung, whatever the grade label says.
• A mastery map you can show. Per-topic records of what is mastered, in practice, and due for review - useful for portfolios and end-of-year reporting.
• Spaced review built in. Topics come back before they fade, without you keeping the schedule.
• Printables. Worksheets with answer keys, free with or without an account.
• Tests when you want them. Timed mock SAT, PSAT, ACT, AP, AMC, and state assessments, graded instantly with review.
• Reading ahead is allowed. The lesson library is ungated: a curious kid can read ahead of their rung any time.
