A slightly unorthodox opinion, which I wrote years ago and shared with NCTM yesterday. I still stand by it.

#nctmsd2019 is about to start. Lots of tweeting going on, so I'm joining the crowd.

Spoiler alert! The orientation session is going to include a t-shirt cannon. #NCTMSD2019

Wow...look at how we interact with students! #NCTMSD2019

Here's my #nctmsd2019 selfie with Jo Boaler. That's her under the 0.

Today's the day! #apsEPIC #dothemath

Thanks to @achievethecore Barbara Beske Arpi Lajinian @k8nowak for a great webinar and a great opportunity! #coreadvocates #MTBoS

Excited to see the high level tasks our high school teachers bring to pD today!

Tacony Academy students are inventors. One second grader loves #Eureka so much she invented her own personal whiteboard.

For math teachers who grew up in a procedural answer-getting tradition, there is a real challenge in understanding a conceptual approach to learning mathematics. How might we learn to see the "new ways" as something deeper than just another procedure? #MTBoS
