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. 🎉

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
