Short adaptive missions for PreK–5. Kids earn parts, open chests, and assemble robots, unicorns, dinosaurs or fairies. No ads. No chat. Math only.
Free tier included. Grown-ups handle upgrades — kids never see prices.
Practice is organized around Common Core domains (not a certification claim): operations & algebraic thinking, base ten, fractions, measurement & data, and geometry — by grade.
One household plan. Kids never see checkout.
