"But It Looked So Good: Checking On Student Thinking"
They have lots of names: exit tickets, cool downs, show what you knows. Here's why I think that quick, low-stakes formative assessment at the end of a lesson is so important. (told through grade 3 fraction work)

wait, I was already following you, but now I'm VERY SOLD. 💛

I finally finished making an audiobook for Rethinking Disability and Mathematics. Only two years late! Hurrah! I also made some resources to go with it, like Math Homework (a printout with all the math problems in the book to use before you listen or read) ♾️

Original German WWII enigma cipher machine. $330,000.
A display with educational pieces and also artifacts for sale, including a functioning German WWII enigma machine.
My husband stumbled upon an enigma machine for sale at a tech flea market today! (Only $330k! There was a replica for just under $2k. Lmk if you want to hit up Tom for either, I guess.)
Excellent takeaways!!
!! Love these! I’ll look closer later.
Hahaha I think even building off the word “ranch” it wouldn’t quite fit.
Other ones that seem too long that I tossed around: Wedekind, Champagne, Vakharia.
Zimba?
My name might be the lowest scoring. 😂
Kazemi is a good one! Zager comes close with avg points per letter, but Kaplinsky might earn slightly more, depending on the placement of bonuses. Would Tranchemontagne fit on the board. 😂
Thank you, Jeremy! 💛
It sounds like these legislative measures can save lives. I highly recommend checking out the article -- and maybe sending it to your representatives. 🧵/6

But perhaps that's my bias. We live in a state with strong gun control, and my stepbrother Alden still died by suicide with a firearm in our parents' home. None of us knew he had a gun.
My kids were born after he died, but they ask about him. We listen to some of his favorite songs. 🧵/5
I would never want a student to be surprised that a data set is about something like suicide, so it would need to be one of the first things shown -- not a later reveal. Even with that, I worry that these numbers suggest that it's not a hypothetical to some students. They know people. 🧵/4
I post graphs that use difficult data sets all of the time. When in the hands of an expert facilitator, these can spark powerful conversations. The facilitator has to decide when to intervene, and when to let a difficult conversation unfold. They need to support students in talking about bias. 🧵/3
In a 49-year state-level analysis, handgun permit laws, waiting periods, and concealed carry license requirements were associated with lower firearm suicide rates.

I follow a lot of accounts that post data visualizations, where I find potential slow reveal graphs.
This is data that I want to share that I will not be turning into a SRG. Still: it's data that I think you should see, so I'll explain why. 🧵/1

A heatmap highlights the multiplications kids aged 5-8 most struggle with. 11 times 11, 8 times 4, 8 times 6, 12 times 8, and 6 times 8 are all the most challenging.
Quick! What's 6 x 8? 7 x 6? The trickiest multiplications for kids aged 5-8. How many do you still struggle with?

Missed opportunity to make that thing flippable (well, with rotational symmetry)

I’d rather have the hierarchy of quads neatly in 4th, too. I guess it’s to provide a spiral for thinking about hierarchy, in general, but we always want to do more but then it’s a much bigger lift.
Why would it be in grade 3. 😭 I haven’t looked much at NWEA.
I have talked with kindergartners about square corners in shapes, so I think it’s a longstanding idea! Not new to 3rd. It’ll need to get addressed, regardless. The concept of an angle is complex, so I’m okay with it staying in 4th. The classification stuff in third is tricky to me, too.
I’ve always introduced parallelograms in 4th, when we do parallel lines.
I used to introduce the term “right angle” in third, because it seemed expected magically between 3rd and 4th, but I think it’s better as an explicitly taught term in grade 4 alongside the concept of an angle.

DESE has a lot of explaining to do.
This likely would have gone unnoticed if not for a diligent teacher working over the summer to validate DESE's mistakes.
I ask this at every talk I give:
To what extent are we placing our students' futures into biased, pseudoscientific, noise machines?
