Overview
Zearn is a nonprofit online math platform for grades K-8, built around the Eureka Math/Engage NY curriculum that's used by thousands of U.S. Public schools. Free for individual families to use online (paid tiers available for advanced features). Each lesson combines a video tutor, interactive practice, and printable worksheets. Designed to align with school-grade scope and sequence. Particularly useful for families using charter funds or who anticipate re-entry to public school; the curriculum is what schools expect students to know. Less playful than Beast Academy, more rigorous than MobyMax.

- •Free version has limitations. Full features require paid license
- •fully standards-aligned approach may feel too school-like for alternative education families
- •digital component requires devices and internet
- •K-5 only. Requires transition to another program for middle school
- •some operators report the digital lessons move too fast for struggling learners
- •Eureka Math's reputation is polarizing. Loved by math educators, frustrating for many parents
Best fit for
Microschool operators wanting a free or low-cost rigorous math program aligned to Eureka Math; programs needing a hybrid digital + paper math curriculum that balances screen time; operators wanting built-in assessment and progress tracking without manual grading; charter-adjacent programs needing standards-aligned math documentation
The honest read
Mentioned in microschool operator communities as the rigorous free math option. Operators who want standards-aligned math without paying for Saxon or Singapore gravitate here. The Eureka Math foundation is both its strength (genuine mathematical depth) and its liability (the 'new math' approach frustrates traditionally-minded families). Best received by operators with math teaching confidence who can supplement the digital lessons with concrete manipulatives. Not the community favorite but respected as a free option with real substance.
