BrainBucks is a free, web-based learning platform designed to help kids in Pre-K through Grade 10 build skills in math, reading, and more — while earning virtual rewards for every correct answer.
We combine adaptive learning with a simple reward system to keep kids motivated. As kids answer questions, BrainBucks adjusts the difficulty automatically — moving faster when they're ready, slowing down when they need more practice.
Alongside the practice site, we publish free guides for parents and teachers on math, reading, spelling, geography and science, each with practice problems and answer keys. Browse them in our Learning Guides section. Guides are written and reviewed by the BrainBucks team, and we update them as we receive feedback.
BrainBucks is an independent project built by a small team passionate about making quality educational tools accessible to every family, for free.
We take children's privacy seriously. BrainBucks is designed to be COPPA-compliant — we collect only the minimum information needed to run the platform and never sell or share personal data. Parents are in full control of their child's account at all times.
