One thing I’d like to see more of in math education is an appreciation for practical consumer math. For example, suppose your favorite cereal brand unceremoniously starts arriving in a smaller box.
Students should learn to be on the lookout for things like this. They should develop a quantitative curiosity, exploring the various ways that quantity can be disguised.
And ultimately be able to put together a real quantitative analysis that helps them make good decisions.
This is math that everyone can use!
