“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)

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

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

Thank you so much for joining us! 🙂

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

Dee and Grace!

So fun to see @gkelemanik.bsky.social!

Come on in to Sydney Marcus to hear @dingleteach.bsky.social! Let’s envision enacting real equity in our learning spaces! #NCTMATL25 #AntiRacist

Hey, #NCTMATL25! Head to Game Night for some math fun and to check out the @todos-math.bsky.social info!

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

Will you be at #NCTMATL25 this week? Come find the TODOS booth!

Oct 15-18

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.

Front of a green t-shirt with an outline of Georgia in white, filled in with black. There is an “X” to designate Atlanta and the text “The new math is black”

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

@nctm.org I am on my way! Atlanta here I come! #NCTMATL25

She is always a great way to start a day! 🙂

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.

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.

Q3a: What mathematics do you see in this object? - symmetry

Q3b: What makes this art? - symmetry

Feel free to slow chat re: any of it that speaks to you! #ElemMathChat #MathAndArt

Thank you in black text in a white circle surrounded by multicolored flowers.

Let’s keep making and noticing patterns in mathematics and art!
Thank you for joining me this evening! #ElemMathChat #ArtAndMath

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! 🙂

Mixed-media art piece- paint, textile, and paper on canvas- in green and shades of brown and burgundy

Q7: What patterns do you notice in this piece?
What other mathematics can we pull out? #ElemMathChat #MathAndArt

Yes!! So much math and science in what you are describing! #ElemMathChat

Celica Crifasi- porcelain tile cookies- Geometric patterns in blue and white icing

Q6: What art do you see here? What mathematics do you see in this art? #ElemMathChat #MathAndArt

Q5: What do you notice about this image? What do you wonder?

Q5b: How do the patterns in the tiling contribute to your appreciation of the art?
