A reader wrote in to ask what to do with a math lesson about reading analog clocks. **What happens when a student can already read a clock just fine?** Can we cook up a fascinating math project about clocks?

I love to simple ask, “*what’s interesting about clocks?*” “Interesting” is a powerful enty point for designing a math project?

### An Interesting Clock Project

So, what is interesting about clocks? To me, it’s gotta be the odd time units! **Why do we divide time into units of 24, 12, and 60?**

I will investigate the origins of units of time used across cultures and create a presentation [or an essay, or a comic strip, or a skit].

Now, while you work with on-level students, your students are exploring an intriguing topic that might take her to Ancient Babylon *and* introduce her to a base-60 number system!

And this will lead beautifully into that lovely question: “What if we made a *new* version?” After seeing how Babylonians, Mesoamericans, and Chinese developed systems for tracking time, **could we make our own units of time that divide the day evenly?**

Now we’re cooking!
