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!
🏀 #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. 🎉 www.si.com/college-bask...

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
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." mrrowe.com/2025/02/28/w...
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…

💡Ideas please! How do you build writing skills ✏️ in math class? And by writing skills, I broadly mean *everything* -- from just wielding a pen or pencil, to communicating arguments in written/visual form so that someone else can digest them without spoken explanation. #ITeachMath #MathSky #EduSky
