Curio Class is a cabinet of interactive tools for K-12 classrooms. Every tool is free to use, share, download and adapt. There's no premium tier, no sign-up wall and no "unlock the full version."

Teachers already spend their own money and their own evenings on their classes. Good interactive material shouldn't be one more thing to pay for or one more account to manage.

What we make

Tools you can put on a projector, hand to students on Chromebooks, or carry on a USB stick. Some are games. Many are simply good to explore, like a periodic table you can spin and light up. None of them are a quiz bank.

How it's built

Every tool is a single HTML file that works offline. Each one is aligned to the national standards framework for its subject, so it fits whichever state you teach in. Tools we've planned but not built yet sit on the bench until they're ready.
