In June 2025, I continued to explore radial designs by arranging heptagons around a central hexagon in a new arrangement! #21CenturyPB #iTeachMath

On a fun side note, I've been working on a new board game with my brothers. Really a fun project :-) We'll Kickstart it in 2026 (first Kickstarter in over 5 years!). Take a sneak peek below. You can also sign up to get notified when we go live! www.kickstarter.com/projects/fin...

#ITeachMath SO MUCH MATH

Made a site comparing the sizes of living things :) The great Julius Csotonyi spent 5 months painting over 60 illustrations for the site, no ai used > neal.fun/size-of-life/

The real deep cut in this comic from @smbccomics.bsky.social is the 37%. That's a serious math reference right there. www.smbc-comics.com/comic/capita...

It's Mental Math Monday with @mikeflynn55.bsky.social. How would you mentally calculate 88×8 without using any 8s?

This month I’ll be sharing some of my favorite designs from 2025! #21CenturyPB #iTeachMath

This is how we organised the Prime Climb board at One Hundred Factorial today. (cc @mathforlove.bsky.social ).

"'6yo: If 0 + 0 is 1, then would 8 times 0 be 4?' ... These “What if” questions are a sign that a child is taking a sort of radical ownership over their mathematical thinking. ... He wants something to be true to explore an idea, so he’s just doing it"!

Happy Friday! Finally had time to write—latest post on having students create the questions: fawnnguyen.substack.com/p/when-stude...

We've recently been playing a modified version of Prime Climb with our son. If you have Prime Climb already and want to try playing with younger players (i.e., 6+), try out this version. It's been really fun! mathforlove.com/2025/11/prim...

Love to see this press about another Math Room from @mathhappens.bsky.social! www.fox8live.com/video/2025/1...

My 6yo asked me this morning: "If 0 + 0 = 1, would 8 times 0 be 4?" I wrote a blog post about it. mathforlove.com/2025/11/big-... #tmwyk #iteachmath #mtbos

I love working with figurate numbers (see my Square Numbers handout mathinst.com/squareNumbers) esp. Triangle Numbers w/my students but never thought of @mathforlove.bsky.social's 'Step Numbers' (mathforlove.com/wp-content/u...) which now seems obvious to consider! #mathisfun #mtbos #iteachmath

Just in case any of you think my manic enthusiasm for the artistry that is Outer Worlds 2 is exaggerated... This is ONE of 20+ fully original songs I have heard so far on the 3 in-game radio stations you can tune into as you play. www.youtube.com/watch?v=eguC...

I always smile and think of @sneffleupagus.bsky.social every time I pull these out and use them for tutoring, which is a lot. I sure am thankful she suggested I get these a few years ago! They are SO helpful!!!!!😊

Did you know completing the square literally means to complete the square? I didn't when I was in high school and that would've made it so much easier.

Just arrived in Atlanta with these new shoes that I designed using Tile Farm studio. The tessellation on them is related to the truncated squares Archimedean tiling. If you come by the Tile Farm booth at @nctm.org this week I’ll show you how I made them! #NCTM #NCSM2025 #iTeachMath #Tessellation

From #RaceToNowhere to #CountedOutDoc, one thread connects them all: how belonging and self-belief shape mental health. On #WorldMentalHealthDay, let’s design systems that nurture confidence, curiosity, and connection so no one feels “counted out.” 💚 #FilmForChange

This graphic novel is astonishingly original, brilliant, and a joy to read - it actually illuminated my understanding of the original Beowulf. You should get it!
