This page works with the Introduction to Binary Numbers Teachers' Kit, but please use it for anything interesting or fun!

Much as I hate to say anything browser-specific, this page works best with Firefox. If the cards "misbehave" in Chrome, reloading the page may fix the problem. The animation isn't quite right in Microsoft Edge.
