Not trying to make it sound like I'm degrading students' intelligence, it just seems like something so fundamental to know, regardless of era.
I had like three 7th-grade students in my last period on Friday ask me what time it is. This was for a band class, where all the students face where the clock is behind the conductor's podium, so it's not like they don't have a clock available without their phones/laptops. I've subbed at elementary schools where there is either a lesson or a chart hung in the room about telling time, so it's not really a case of schools not teaching it (unless it's a case of different curriculum in a different area within the district, but I doubt it), and I'm sure, at the very least, the parents would've went over it with their kids at some point in their childhood. I'm fully aware that in a world of growing technology, analog clocks aren't often used, but what about an instance where that's not an option, depending on the building that they may work at in the future?
