How to Use Big Number Academy

Big Number Academy is a calm space for exploring big ideas at your own pace. There are no scores, timers, ads, or right answers.

Interactive Games: Explore big numbers through playful, calm activities.

Number Stories: Listen or read gentle stories about big ideas.

Videos: Short, calm videos that explain big numbers in simple ways.

You can explore in any order, there’s no set path.

About the Beta

Big Number Academy is currently in beta. That means it’s still being shaped and improved.

The feedback form is there for parents — not to report problems, but to share what feels helpful, confusing, calming, or unnecessary.

You don’t need to use everything, and there are no right or wrong ways to explore. Even small thoughts help guide what the app becomes next.
