Testing is integral. Performance gets reviewed. True in scouting as well. You get badges, like grades in some ways.
In the school where I teach, you keep failing until you pass but that can take variable time and there's no cohort moving through. You're more or less on your own, and if you have a busy life, it's OK to lag back. You move forward when you do. Correspondence schools gave rise to this pattern, while computers sped it up like crazy.

Yes, that's how they'd carved the turkey back then. Math was for brains and shop was for "below grade level". The ethnic stereotypes abound.
Lets say the girl scouts are out placing sensors where others have gone before and saved coordinates (lat / long). Not only is GPS involved, but what the sensors measure, how readings go through a pipeline ending in visualizations (matplotlib). Water and air quality. Environmental models (half life, decay, rates of change, exponentials).
How deep is their math and physics? Depends what you measure.
Does proficiency include some ability to handle tools and build things? Not in every school, no.

Playing chess is not math, and yet mathematicians study chess. Or by some liberal definitions, playing chess is a form of math play, likewise Go (the game), but where do we draw the line? Are people in casinos "doing math"? "Casino Math" is real enough (probability, permutations):

High school literature should include traversing some 20th century lit, e.g. Ezra Pound, Hemingway. Discuss their different dealings with Fascism as a concept (Hemingway in Spain, Pound in Italy). Readings from 'The Pound Era' by Hugh Kenner, a James Joyce scholar, connects us to Bucky Fuller and those dots (Kenner wrote 'Bucky', a bio, and also 'Geodesic Math and How to Use It').
So yes, if we start cranking out the icosahedral numbers 1, 12, 42, 92... in World Languages class (Unicode, ASCII...), using a computer language (OCAML), that won't have to be considered math nor run by the math department teachers for approval. It's Lit.

Sadly. Home Ec either, which needs to merge more with Urban Planning and Ecology. Where is the food coming from, what lifestyles does it support, how does a restaurant work, a grocery store? Inventory. Trucking. These are all Supermarket Math:
