No math in this, but I was frustrated that there wasn’t a way to disable the “next” button to keep students from progressing until they’ve mastered an important concept (or at least until they’ve given it a few tries).
This took forever to code, but since it all takes place in one screen, there’s no way to skip ahead to the result you want. You just have to keep pressing buttons (or not pressing them) to accomplish your desired result.
The second slide on the activity will eventually use similar code to create a situation where students can’t see the next clip of a video until they correctly answer a multiple-choice question about the question they just watched.
EDIT: Have since used the feedback here to update the Button Game! Slide 2 has the “doneness” factor, slide 3 uses the “hidden” feature, while slide 4 uses the “coverText” feature. Thanks, all!
