As with all things, there are infinitely many contributing conditions. It's clear that #MTBoS magic hasn't been recreated anywhere. Whether personal/global circumstances, career changes of many #MTBoS veterns, or subtle shifts in why people use social media. So: How do we make new magic? #iTeachMath

New Post: Simple thoughts on one of math ed’s biggest hot buttons. natbanting.com/blog/memory-...

How sharp are you? Take the new quiz: emo band OR cognitive bias

Thanks to @jennalaib.bsky.social , @natbanting.bsky.social and others for the inspiration to do a fractions clothesline. My student were very engaged! #ITeachMath

@natbanting.bsky.social looking forward to your keynote at my school tomorrow!

Also, kids just get lost in some Amplify dashboard with no option to enter code for activity. There’s probably a simple fix here…

So how do I find my dashboard of recent @desmos activities? Students seem to be sent every which way now that Amplify has added a layer of administration.

Has anyone built a math practice app where every answer is 6, 7, or 67 yet?

Visual Patterns 🤝 Pattern Blocks I am currently OBSESSED, in a (mostly) healthy way, with @fawnnguyen.substack.com visual patterns and @mathforlove.bsky.social pattern blocks for kids to learn and create patterns. Ah-may-zing. Also, I am in LOVE with Mary Vail's Thinking Desks, they are phenomenal!

[New Post] Ontario Math Links - My favourite #math related links from this week: ontariomath.blogspot.com/2025/09/math... links & help from @mrcorleymath.bsky.social @mathsweek.scot @darrenmacey.bsky.social @natbanting.bsky.social @maria-naturalmath.bsky.social &more #MathChat #MTBoS #iTeachMath

I think this is all sorted now! (That’s 5 hours of my Saturday I won’t get back 😂)

I wrote a new post yesterday: natbanting.com/play-with-yo... It’s about the benefits of teachers tinkering with the problems/prompts we offer students. (And, tangentially, about the benefits of conference spaces where we are given license to do so) #iteachmath

“Orange” is a 1-syllable word (Massive family argument occurring)

Any old #bcedchat folks have a lead on a veteran math history teacher??

BC has a grade 11 math history course!! Have any BC math educators on here taught this course? If so, what was your experience?

Math class: “Here’s a task about a hallway of lockers that involves perfect squares” English class: “Here’s a book and, at the end, the hero dies” These are identical experiences imho I think math teachers feel an increased need to include more “spoilers” to justify openness in their classroom.

It’s true what they say. This is excellent. And I’m going to quote the end to give you a taste: “But personalized learning is the wrong ideal. … We shouldn’t be going all-in on kids learning on their own. We should be trying to figure out how to make whole-group learning even better.”

This exhibit at the Tate Modern in London giving real “How Many?” vibes. @triangleman.bsky.social

Re-sharing from Feb ‘24: @natbanting.bsky.social waxes poetic about the Math Twitter Blog-o-Sphere (RIP). Man, that was a heady scene. It felt like an open apprenticeship for those of us on the periphery. I love seeing so many good folks emerge from it. #mtbos natbanting.com/rip-bos-a-tr...

Looking forward to reading! Here's my latest, on the importance of our connections to each other (thank you for being in my group of math people!) karendcampe.wordpress.com/2025/08/05/f...

Finally! An AI that gets me.

I don’t think people read blog much anymore, but a week in a library has produced a few new ones for this school year. Some thoughts that have been ratting about in my head for a while.

Here’s a thing about teaching post-secondary: After the course, you’ll get emails expressing how enjoyable the course was. You’ll also get the odd one saying they disliked you and the course. The former are sent immediately; the latter are sent after grades come out. Pay attention to both.

👀 the license plate

**overheard at Starbucks** Customer: “What’s the wifi password?” Barista: “1-3-5-7-9. All the odd numbers.” C: “That’s a lot of numbers to remember.” B: “It’s a pattern. Once you see it, it makes sense. But until then, it’s just a bunch of numbers.” Friggin’ profound advice re: math education.

We’re currently under a severe thunderstorm watch here in Alberta. I love this handy guide which clearly explains the difference between a “watch” and a “warning.” #yegwx #abstorm #yegweather

Oh dang. This little piece of writing holds up pretty well. christopherdanielson.wordpress.com/2015/07/26/f...

Has anyone found a replacement for Google Jamboard? I need a free, simple online whiteboard collaboration tool.

Hi Blue Sky! I edit the Journal of Humanistic Mathematics. We publish articles, essays, #fiction & #poetry on doing, teaching & living of #mathematics. So far we had more than 700K full-text downloads of our content - why not check us out? scholarship.claremont.edu/jhm/ #math #openaccess #mathart

An amazing gift from our MS faculty 🥹

Time to shave the playoff beard. Means that the sprint to graduation is on!

My top three quotes from #OAME2025 - figuring out what students did and whether it makes sense is very mathematical work. - Using AI to bypass the learning isn’t the same as using AI to engage in the learning. - Intention energizes; attention transforms.

Fearing "back to basics" talks circling Math education here in Ontario (because what does that mean?). @natbanting.bsky.social in his keynote speech on (re)defining "basics" as mathematical thinking; 4 A's to nurture student mathematical decision making is a focus on basics. ✅ #day2 #oame2025

The Boy claims that “x is 3” I claimed otherwise. www.instagram.com/reel/DHT-IsQ...

🔑🚪It’s time to escape! Check out the newest Desmos escape room! To play yourself: student.desmos.com/join/3jjxj9 (no need to log in but it will save your progress if you do) Here’s the teacher link to run it with a class: teacher.desmos.com/activitybuil... Have fun!

Today a student came into class and hurried up to the front to exclaim: “Guess what?! Today’s my last day at Kumon!” We then high-fived and the entire class applauded. I will cherish that moment forever. (She did not need Kumon’s toxicity in her life)

What is Rice? If you're dragged into an argument against @natbanting.bsky.social (thanks @carterorieux.bsky.social ) a sure fire way to make it 10x more fun is getting his students in on it. 77 students contributed their thoughts to explaining their thoughts on rice and a few helped me hang them up

Teaching is fun because one students says, “oh that makes so much sense! Thank you!!” and then ten minutes later another student says, “that shirt makes you look even more pale than usual.”

HELP!!!!! The Boy (Gr 5) and The Girl (Gr 2) are currently fighting over a piece of paper to show some math they learned today. She wants to show subtraction regrouping and he wants to show division by partitioning. I want to stop the fight but my heart is too busy EXPLODING WITH JOY

I'm so excited for #SUM2025!

My hometown conference is this Monday. Oh boy does Sask Math Ed have some talking points to confer on. #SUM2025
