“It’s no longer enough to mean well; liberatory teachers must do well.”
@robertqberry.bsky.social sharing the work of Teachers in the Movement- an oral history of teaching in the Civil Rights era. This work is important and very needed in the current moment. #NCTMATL25

Johnson: "Grijalva should be working for her constituents right now. I don't know what she's doing. I keep seeing their political stunt videos. She should be in her office. She should be working or in the district for her constituents" (Grijalva is not in fact a Rep. b/c Johnson refuses to seat her)

What a great experience presenting with Kyndall this morning! Thank you to the folks who turned out to think about big issues and the mathematics that helps us understand and work towards solutions. #NCTMATL25

Slide reading “Elevating Professional Learning While Using Mathematics to Advocate for Sociopolitical Change” behind Kyndall and Dee (the presenters)

Teach for Brilliance, Not Deficiency!
Equity without rigor is empty.

Amen, @doctorkchilds.bsky.social!

Expect brilliance… and we will get it.

Children must feel seen before they can be challenged. We center identity.

See the whole child!
@doctorkchilds.bsky.social started off with this important truth. #NCTMATL25

Why do right-wing adult males get to be “kids” and the benefit of everlasting adolescence?! NO- we don’t have to allow this. #OldEnoughToKnowBetter

To my math folk at NCSM/NCTM this week, keep an eye out for #PlaceValue. I’d love to hear how people replicate and refine the ideas Marian Dingle (Atlanta family) and I explored prepping for Chicago 2020 and Atlanta 2021, you may even find sweatshirts out there.

Anyway, if you go - let me know.

I’m here… and have my shirt to wear!
I looked through some of my notes from way back when. Wow, time really is all kinds of messed up! #NCTMATL25 #PlaceValue

The House Majority Whip is also insisting that a peaceful "No Kings" demonstration is in fact a "hate America rally" held for the "terrorist wing" of the Democratic Party.

Really feels like they're trying to manifest a violent reaction to it.

Emmer: "This is about one thing and one thing alone -- to score political points with the terrorist wing of their party, which is set to hold a hate America rally in DC next week."

If a grad or undergrad researcher in my lab said to me, "We are doing the studies to make the proof", I would have them retake research methods course and/or a philosophy of science course.

Let’s end with some mathematical philosophy.
G.H. Hardy said, “A mathematician, like a painter or poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made of ideas.” (A Mathematician's Apology, 1940, pg 13)

So much to think about in the gradients of both of those! 🙂
