We just ran a family math circle inspired by the math notes from the book at UNC-CH. We worked on activities with infinite variations: defining hard-to-define things (sandwiches, life), and rebuilding solids from projections. So much math joy! My slides: docs.google.com/presentation... #iTeachMath

The latest update on AL, Logical's Kickstarter talks more about the math notes which follow the story. www.kickstarter.com/projects/nat... Readers want to know more, and these notes are a support for them and for teachers who want to lead related activities.

Last #mathinaction, Zach Cresswell, z-cress.micro.blog, bit.ly/2026gvsumia 10 things I wish I knew 10 years ago

How'd I miss her tag? @tmaynard5.bsky.social bsky couldn't find her before. Amazing #miched leader and mentor to our PSTs as well as the best classroom teacher.

Howie tried explaining it here: bsky.app/profile/howi... But for building understanding, I use area model or list out combos of factor pairs. #iTeachMath

Hate it because in the process you write expressions that aren’t equivalent

#mathinaction participant suggested First Five www.edtomorrow.com/today/ anyone use these?

#mathinaction next Cultivating a Positive Classroom Community through BTC Practices, Clare Bunton & Josh Zolen. Opener, minimum number of squares to fill an 11x13 rectangle. Great group worthy question, lots of approaches. Next: Thin slicing to develop instruction.

Next up #mathinaction keynote Desiree Harrison, The Tomorrow We Choose: Teacher Agency and the Decisions That Shape Mathematics Opportunity. Her podcast kids math talk www.kidsmathtalk.com/podcast @kidsmathtalk.bsky.social

Tara in side conversation recommends Algebra by Example www.serpinstitute.org/algebra-by-e... #mathinaction

No better way to start #mathinaction than with Tara Maynard on vocabulary in math. She's been 28 years in the SAME ROOM. Using socrative to start us off with a T/F quiz. Do you spend quality time teaching and having students use math vocabulary?

I think Harvard's plan to respond to the every-decade moral panic about grade inflation by capping A's is pedagogically obscene. Grades should be a measure of learning, not competition. Grade caps engender competition and anxiety where we should be teaching collaboration and a love of learning.

Sample chapter from AL, Logical posted at the Kickstarter page! Please peek and share! www.kickstarter.com/projects/nat... #mathstory

This afternoon was the "Hands-On Activities" portion of the conference. I brought the supplies (150 laser-cut pieces of wood, 1000 yards of yarn, wood glue, and 50 binder clips) to make a giant cardioid and a giant nephroid. It was fun, and I think they turned out great.

Some slick Vasarely #mathart mapping in #geogebra from Daniel Mentrard. dmentrard.free.fr/GEOGEBRA/Mat...

Saw a simple, sweet puzzle that I saw on FB, which FB took away before I could credit it! Anyone know the source? #geogebra www.geogebra.org/m/wprjzhq3 #mathplay

@jamesenge.bsky.social collectingtrek.ca/2019/01/07/a... pretty cool, new to me

But of course, @zachweinersmith.bsky.social is making the real #mathcomic www.smbc-comics.com/comic/prime-2

. @mathgarden.bsky.social posted the top image, which begged for a #mathcomic www.tumblr.com/talkingnumbe...

We were invited to read from our books, which I did of course. But first I had some opening words, which I thought I'd share with you here. I'll share video too, once that's available.

I like to imagine this was for an early version of the two dice sum #mathgame

I was gifted a gorgeous origami sculpture of five intersecting tetrahedra. This inspired me to recreate it using Desmos. www.desmos.com/3d/m7hqyu2gpr en.wikipedia.org/wiki/Compoun... @desmos.com #iTeachMath

If you ever look at the history of education, you’ll see that any initiative where the most marginalized people got an education, so did many others. Diversity, equity, and inclusion are all pillars of the America people wish we had. And the one we’ll keep fighting for.

#mathstoday some great discussion of a Don Steward 3-fer. Those triangle puzzles are great and can be set for a great variety of challenge. donsteward.blogspot.com/2017/02/frac...

7/12 of the way there! AL, Logical on Kickstarter. kck.st/4ru1Sky #mathstory #iteachmath

Yay! #mathstoday one of my PSTs chose my #slowrevealgraph (made with @jennalaib.bsky.social's help, of course). slowrevealgraphs.com/2026/02/09/2... Most of the discussion was about what the thickness of the bands meant. Made it a stumper even after they got the olympic connection.

Stats #mathgame playtested with my PSTs and Hope Gersons. docs.google.com/document/d/1... Pretty fun. If you try, I'd love to hear about it!

Love seeing @jennalaib.bsky.social using this framework. I learned from @deltadc.bsky.social . Often ask learners to pick one to consolidate thinking. Applying to planning is great. www.youtube.com/watch?v=1dH7...

Doughnuts for the fraction class #mtechat

Another great MRC. Though now I need to see @mfannie.bsky.social singing a funny song with her band.
