Couldn’t help but to post a behind the scenes of this month’s #elemmathchat with @ryanflessner.bsky.social because when else will that be possible?

If we don’t believe they can, they won’t. Students, teachers, administrators, schools…believe they all can, and they will.

Watching the collaboration and a-has as participants engaged in thoughtful mathematics in my sessions at #ICTM25 is why I love the work I do. So incredibly grateful for educators who devote time to learning. Your students are just so lucky.

#ICTM25 was a great weekend full of lots of learning and laughs. @ryanflessner.bsky.social and I had a great time as emcees. Special thanks to our 4 awesome keynotes @robertkaplinsky.com, @drindiagrit.bsky.social, @kimrimbey.bsky.social, and @howiehua.bsky.social for indulging us in stage selfies!

It’s like the advertisers know what words to use to get to me. Regardless of accuracy of the actual math. It didn’t work. This time….#iteachmath

I have a lot of emotions about posters like this & divisibility rules in general. Mainly, I don’t know most of them b/c I can’t remember them and I have other ways to figure out if a number is divisible by another. Can anyone help me reconcile my emotions? Does knowing them help anyone? #iteachmath

Guiding third graders and listening to them talk through a visual image from @gfletchy.bsky.social and @tracyzager.bsky.social BFF kits this week was a treat. They literally did everything you would have wanted them to showing teachers that yes indeed, they are capable of this kind of thinking!

Students are in a classroom looking at a visual image projected on a screen of a 6 by 4 array of toy cars. Some are pointing at the picture. Teachers are observing them think together.
