The June cohort of the Citizen Math Online Launch Course kicks off June 17th - There's still time to join!

This is a great experience for those looking to level up their real-world 🌍 convos in math class. #EduSky #MathSky

Thanks for sharing this #RealWorldMath gem! 💎 If you've got one of those wonky end-of-year-schedule-cant-really-plan-for-it days, this article could spark a great discussion!

ALSO - The thing about the implied gov't chip in is that it is a zero sum game...it's less money into [whatever program] which makes it harder to budget tax breaks for working folks while maintaining the same level so social support. -G

It does! I (Ginny) took a break from the socials and missed this gem, but thank you for sharing. And holy heck are there some great conversations to have in math class around this.

Hey #iteachmath! You know what was a great idea that sort of died, the #observeme trend. I have always thought the best PD is watching other great teachers. We need to bring that back!

Empirical.

Someone Finally Won Warren Buffett’s $1 Million March Madness Prize Thanks to Rule Change It’s not a perfect bracket, but it’s close enough.

🏀 #RealWorldMath Finally! Buffet's updated challenge was to pick 30 of the 32 first round games correctly...for $1M!💰

Would you agree that's 4 times easier than predicting all 32 games would have been? #MathSky #MathsToday

Congrats to the big winner. 🎉

It sounds hard...
Wait!
Have I done it?

That seems fun -- and it's good to have that sometimes. :-)

Has anyone ever partnered with another prof or institution and had students share their work with another class or externally?

Wondering what kinds of IRB/FERPA stuff you have to work through to get this to work?

Eg. Communication stds making infographics and sharing with external science stds

@hbus.bsky.social This intersection of topics looks right up your alley. -G

I know it's not the point, but I think it's cool how effectively she's wielding math/quant to express her feelings with this response. -Ginny

When Problem Solving Leads To Problem Stalling So much of mathematics is focused on the end point: the answer, the solution, the proof. We attach so much emphasis on the destination — the more efficient the better. We place such high value on t…

This is so so good. Thank you, John.

"We focus on diagnosing what’s blocking them from the solution. But in doing so, we miss an opportunity to empathise with their current condition and their mathematical thinking so far."

"Write a Pi-ku." Ha!

Unless you're celebrating with actual 🥧 pie...we're not trying to spark a math-class-induced diabetes epidemic. :-) -Ginny

Here's another #PiDay gem shared over in the CM Community. #MathsToday #EduSky #MathSky

Everyone should see “Counted Out”, a film by Vicki Abeles. This Pi Day (3/14), I'm moderating a panel after the screening at UCLA.

Register for the UCLA event here:
