I’m working on a project now where we have to take the topics in algebra 1/2 and geometry (high school mathematics) and connect it to real-world activities in science, tech, business, etc. This has been fun — but harder than anticipated! While some topics are clearly and deeply useful, many topics are very difficult to connect to practicalities. And, conversely, some of my favorite math — math that underpins key technologies we use everyday —just isn’t part of the high school curriculum. It makes me wonder why we teach the high school math that we do— and whether there is a more elegant or effective curriculum we should consider. (For instance, I’m fond of the classical quadrivium)
