About these resources

These are free practice tools for students studying on their own or with a parent, tutor, or teacher. Each one is a single web page that runs entirely in the browser, so it loads quickly on school devices and keeps working after the page has loaded, even on a shaky connection.

Privacy

There are no logins and no accounts. Nothing you type or drag is uploaded, and no student data is collected or sent anywhere. These pages load no ads, trackers, or outside fonts. Where an activity remembers your progress, that stays in your own browser.

How it's made

The content and code are written with the help of generative-AI tools and reviewed by Trisha Kunst before anything is published. If you spot a mistake, please let me know so I can fix it.
