Maybe Celsius?
But also it’s picnic weather in Fairbanks!! …compared with current temps in Verkhoyansk, Russia. 🥶

I’m at #ATMNE25 in a brilliant session about micro moves for disrupting hierarchies and bolstering engagement. Facilitator Emily Allman is modeling these moves beautifully.
Can share more thinking later, but first wanted to tell @davidkbutler.bsky.social that she had us quarter the cross!

Cop slide is looooong! Here’s a photo I took when the playground first opened. There is a twist at the beginning that is still obscured.
Any ideas how to measure it? Like maybe… yarn? That’s a math task in and of itself!

(I love everyone else’s photo dumps! Meanwhile, here I am posting a photo of my hotel room’s trash can. Fascinating messaging!)

A number of sessions left me thinking about communication in math class. Blog posts are brewing…
Oh, and a number of curious things at my hotel had me thinking about communication, in general. Check out this R&B elevator. Is this effective?

Here's what we did last summer. (It turned out: they were about the same. Sigh! I ended up using this with teachers in MN, not students.) But I'm curious whether people go faster on cop slide than other (shorter, less perilous) slides. Field trip!

I love that video! That slide is so popular that it's listed as a tourist attraction on google maps! 😜 Every time we go, there are adults pestering one another to try it out.

And here, we have a display for our school’s Year of the Turtle. We have live turtles in the library — their release date is next month! — and students made this all-school art project in tribute. The goal was to make 1000 sea turtles to show how 0.1% survive to adulthood.

The art teacher at my school is phenomenal. This week alone, she put up two beautifully mathy displays. Here we have some Escher-inspired 3D cubes.

I saw this on a fifth grader’s page:
A diagram of a circle labeled “2 sides.”
I asked him to explain.
“Well there’s an INside and an OUTside.”

This year, I joined NCSS (social studies) as part of my registration for their national conference. (I presented about slow reveal graphs!) Today, their journal arrived.
What a beautiful surprise to see an article from fellow math educator/SS enthusiast @mathillustrated.bsky.social! 🤩

Maaaayyyyybe they’re all from different sets of base 2 objects?
Jk that’s just a nightmare.
Good thing I still have these bad boys in my office! (Look I’m missing a 2^2 block, too)

And 15 followed by 10/20 with a bar over the 0s to represent that they can stretch on forever. The T introduced the idea of strategic vs legal mathematical reasoning. (LOVE her.) it’s such an interesting idea about generating different powers of 10. 🤯

After examining two strategies for 62 qt = ___ gal, the grade 5 teacher asked the kids to offer other names for the solution, which we had as 15 1/2 gal.
15.5 gal
15 gal 2 qt
Then a kid said 1550% of a gallon
And then… 🧵 1/2

I still love notebooks where we write and mess around! Try our ideas! And then, when it’s come to consolidate, out comes the more structured reference notebook.
(Here’s the first photo I found or a student draft of an idea)

It’s a mix of the kids adding in notes and annotating short handouts. The kids know that they can “ask their notebook” when they’re stuck in class. I have a half written blog post about it… but I haven’t been good about finishing those lately.

Earlier this week, a local B&N let my kids co-sign a few copies of my brother’s books for the store. Hope a lucky reader in metro Boston enjoys this very special edition of “Math With Bad Drawings.” :)

A first grader was counting this collection of shells.
“I think there are 100 shells!”
He selected a hundreds grid to prove it to me, and placed the shells, one by one. “56, 57, 58…” then he jumped down: “99, 100! See???”
