We comb through reports and mountains of data to make lessons so you don't have to :-) but here's the 78 page report on coin production from the U.S. Mint. 👇

Bet at least something in this data will surprise you!

Hope to see more from others! 🩵

Did you know it costs more than 3 cents to produce a penny?

The term “seigniorage” refers to the difference between how much a coin is worth and how much it costs the US Mint to produce

Who's up for a round of #DebateMath re this #RealWorldMath 🌍 from the US Mint?👇

Does it seem like the world keeps changing faster than it used to? It's not your imagination. It's #math.

Do you ever wonder what future innovations we can't even yet imagine?! 🤯

What do *you* think is next for communication...is anyone working on digital smells?

👀 Tiny Observation Idea: Using your seating chart or class list, draw a line from one speaker to the next during a whole class discussion.

What do you notice?

Every month or so, we host a #TinyWorkshop 😊 in the CM Community. This month it's about *student-to-student* discourse. #MathSky
