After a brief memorial, laz lit the cigarette at 6:00am. The 2026 Barkley Marathons has begun. #BM100

A white background with two large, irregular black shapes on the right side, resembling ink blots. Five small blue circles are scattered around and between the black shapes. In the upper right corner is a square containing a question mark. On the left side, a yellow speech bubble reads: “What could the total be? What are some possibilities? How are the possibilities connected?” The image is from www.stevewyborney.com.

A teacher friend asked a great question today. I have some ideas, but I'm curious what others think: What's the intended mathematical goal or learning behind these unknown total Splats? @stevewyborney.bsky.social

On Minneapolis in January 2026 I have loved this city for a long time, but never as much as I have loved it this last week. This is a long post. I promise that it ends with some hope for all of us. Over the last month, but espec…

I wrote up a bit about Minneapolis right now, mostly to share with my coworkers and family, but if it works for you, you can share it, too. arbitrarilyclosecom.wordpress.com/2026/01/11/o...

Thanks for letting me know. codap.concord.org/educators/cu...

Is this what you're picturing? www.mathlearningcenter.org/apps/money-p...

An infographic titled “Getting Started with CODAP: A quick guide for teachers exploring the Common Online Data Analysis Platform.” Overview section: CODAP is introduced as free educational software for data analysis and visualization that requires no login or registration. It notes that CODAP is a product of the Concord Consortium. A line reads “CODAP is great for:” followed by three icons with short descriptions: Investigating relationships found in data through flexible visual representations Exploring, altering, and analyzing statistical measures Developing data literacy through cross-curricular connections Below the overview, the guide is divided into four vertical columns: Column 1: Quick-Start Guide Bulleted steps: Go to CODAP and click “Launch” Click “Browse Examples” when prompted Complete “Getting Started with CODAP” (Parts 1 & 2) to learn the basics Column 2: Recommended Starter Data Sets Two linked examples: Mammals: 27 mammals and 8 attributes Roller coasters: 157 roller coasters and 16 attributes Column 3: Resources & Community Bulleted items: Explore more CODAP datasets Browse How-To guides, FAQs, or the User Forum Check out free curriculum developed with CODAP from various partners Column 4: Flexible Learning Options A list of multimodal resources: YouTube playlist Challenge cards Podcast Research article Images Below the Columns Three CODAP screenshots: A table of 27 mammals with attributes such as lifespan, height, and mass. A scatterplot showing the relationship between mass and height. A dot plot showing mammals grouped by diet (plants, meat, both) with markings representing habitat type. Accessibility Box Notes include: “12+ languages” “Compatible with Read&Write and tablets” The infographic provides a teacher-friendly overview of CODAP, highlighting quick-start steps, sample datasets, community resources, learning options, example visualizations, and key accessibility features.

I recently made a digital teacher resource about CODAP for a class assignment. Maybe you can use it! Download the PDF version with links here: bit.ly/CODAPHandout

Screenshot of the cover page of an NCTM Mathematics Teacher: Learning and Teaching PK–12 article titled “Children’s Games and Games for Children” by Nat Banting and Chad Williams. The screen also shows a Canvas accessibility score of 11% with a note saying “This PDF is untagged.”

I am consistently finding that PDFs of MTLT articles are not passing accessiblity checks in Canvas. Is this something that @nctm.org plans to address in the future? Math teacher educators...how do you remediate this in the meantime?

Thanks!

The week one prompt of the Math Photo Challenge. Look for squares. Where to you see square shapes and perfect square numbers? Example photos are dice with square faces and the perfect square number 4 on top, a square sewer grate and square pint boxes of fresh summer strawberries.

It's time to kick off #MathPhoto25 with #squares! Hunt for square shapes and perfect square numbers. Take photos & share on Bluesky using the hashtags #MathPhoto25 and #square. Please add alt text to your photos for increased access. #ITeachMath

Taught myself how to crochet a granny #square today! #MathPhoto25

Omg that was awesome.

This is a great list!

I’ve been using it as a “thinking partner” to help me revise lessons that were a flop last semester. I teach preservice teachers, and I also redesigned a project with a choice to generate a lesson using AI and then discuss how they would improve it. The results were decent.

Front of a handwritten notecard with the following notes: Look for evidence, ask questions. Amygdala doesn't control frontal lobe. Tell it that's a lie. Write down illogical thoughts. Pinpoint what source of nervous energy is. Let thoughts go. Acknowledge it, but don't fixate on it. [illegible] can bring behaviors.

Back of a handwritten notecard with the following notes: Talk about other people to reduce anxiety. Organize thoughts. Slow down. But focus on not [illegible] people. Watch for anger. If angry, don't respond. Just live life.

I found this notecard in the library stacks yesterday, and I just keep wondering about it. Are they notes from a book? A class? A personal pep-talk?
“Pinpoint what source of nervous energy is”
“Let thoughts go.”
“Just live life”

I’m interested!

Racks of CDs with a pop/rock label above them

This happened to me recently, and here’s where I thought we were headed…no questions asked. We made it all the way there before I realized she meant the music store with instruments, not CDs. My elder millennial is showing.

The year is 2025, and a friend invites you to tag along on a trip to the music store. Where do you picture you are going?

Blackout poetry for my trans son created from an Instagram DM that says “You are healthy. You’re young and wonderful. Surround yourself by people who hear and support. You are doing what’s best. Wonder, love, and play and never be undone.”

Turning the hateful DMs into hope.

Illustration of two joyful-looking people waving a trans flag with the title “Transgender Day of Visibility, March 31, 2025”

Today is Trans Day of Visibility.

I'm so proud of my trans kid—for his courage to be exactly who he is every day.

People are trying to erase trans lives, but trans people aren't going anywhere. They are loved, they are thriving, and they deserve to be seen.

Trans joy is real, and it's beautiful.
