"Graphs are 1 of the pieces of math students will interact w/ most outside the math classroom. We should strive to give students a rich & broad conception of all the different ways to represent data in the world." - @dylanpkane.bsky.social on how @jennalaib.bsky.social's Slow Reveal Graphs do this.

New #SlowRevealGraph Billboard Hot 100: Artists With The Most #1s Drake recently surpassed Michael Jackson as the solo male artists with the greatest number of #1 hits. What other artists made the list?

Work from 3rd graders. The lowest answer was the winner. Both selected the correct player, but one for the wrong reason! Answers are only the starting place -- how they reason is so important.

Love the rebuttal! I would love to see a positive framing of a no-phones policy: helping students reclaim their attention and choose not to be the product in the captured attention market.

"Good vibes...make math class a place kids want to be. More learning can happen in those spaces. But we can’t stop at vibes. These short, low-stakes formative assessments let us ...distinguish who is engaged but confused & who is seemingly disengaged but actually getting it." @jennalaib.bsky.social

When do "indicators of a positive classroom experience... correspond with learning" and when do we "use them as a proxy for student learning"? How can formative assessments help us tell the difference? - @jennalaib.bsky.social

NEW Blog: The community a young child lives in & the buildings that are a part of it can be an important part of students’ lives and is ripe for mathematical connections to geometry. This Excursion focuses on designing & constructing block buildings to create a town or city. #Excursions

NEW BLOG POST "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) [link]

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) ♾️ mathematizing4all.com/rethinking-d...

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.)

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

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?

Tonight I heard the amazing Dr. Sara Rezvi speak at Math for America. Loved hearing her talk about the contributions of Islamic mathematicians, with examples from al-Khwarizmi to Miryim Mirzhakani. We used Desmos to look at Omar Khayyam’s solutions to cubic equations. 😃 #MTBoS #IteachMath #MfAProud
