Curious? Start here.
Are these the full classroom apps?
These are short, playable samples built for this gallery. They show a learning interaction without taking you through a full classroom session. Each sample is labeled, and the teacher results demo uses fictional data.
Do I need a student account?
No account is needed for these website demos. Enter answers, try a model, or explore the sample results right in your browser.
Can I try them on a Chromebook?
The gallery uses standard browser features and is designed for current browsers on Chromebooks, laptops, and tablets. The controls support mouse, touch, and keyboard input. Some activities are easier to explore on a larger screen.
What happens to the answers I enter?
These samples keep your answers in the current page. They do not ask for student names or send answers to a teacher. Closing or refreshing the page resets them. See the site privacy note for hosting details.
