New #tmwyk! If you've been following #vehiclechat (or if you've been puzzled by it), here's some more depth and background. talkingmathwithkids.com/blog/on-vehi...

New Blog Post: Inputs & Outputs Reflecting on a session with Amy Lucenta and Grace Kelemanik at NCTM 2025, examining areas of cognition and micro-routines for engagement of all students.

Lovely collection of Same & Different prompts for high school from @karencampe.bsky.social!

By revealing graphs piece by piece, teachers can build student curiosity and guide them to more effectively make sense of data! 📊 #DataLiteracy #EduSky #MathSky

Don't forget about the 100+ free challenging tasks for secondary math teachers at www.map.mathshell.org/lesso... There are around 20 per grade level.

I'm having a blast revisiting Estimation 180 tasks. My next attempt: Cheeseballs day 207. www.youtube.com/playlist?lis... If you missed 206...it's there too. #estimation180 #iteachmath #mtbos

New lesson added to our free lesson library! __The Tax Collector__ This is an expanded writeup of my original @nytimes.com Numberplay writeup from 2015. Features a tie-in to my more recent @ted-ed.bsky.social riddle too! Great for grades 4 - 10. mathforlove.com/lesson/tax-c...

Did the Dog vs People Names scatter plot today with a room full of k-12 computer science teachers, and WOW, the discussion we had! 🤓 #slowrevealgraphs

One of those heart-FULL teaching days: New post: open.substack.com/pub/fawnnguy...

Happy Friday, everyone! Same old me, but my blog has a new home: fawnnguyen.substack.com/p/new-blog-h... Please come by to visit when you have a moment! #MTBoS #iteachmath

[New Post] Ontario Math Links-My favourite #math related links from this week: ontariomath.blogspot.com/2025/05/math... links&help from @mrvalencia24.bsky.social @comapmath.bsky.social @openmiddle.com @robertkaplinsky.com @howiehua.bsky.social @unsolvedmre.bsky.social #MathChat #MTBoS #iTeachMath

Dynamic window size in @desmos.com means that we only need 1 parabola now! Hooray! www.desmos.com/calculator/z...

Canucks have made marketing misstep after marketing misstep over the past decade...but never done anything like this

Join me for "Multiplication: More Than Repeated Addition and Times Tables" at the 2025 @mypita.bsky.social Spring Conference in Squamish on May 9!

Launch for tomorrow's polynomial division lesson. #iteachmath #MTBoS

With CBC now having called all ridings it's time for the land-vs-people-vote animation.

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! 🤩

This is a nice problem for students to think about!

#MathsToday Today was day 1 of logarithms in #MHF4U so I presented students with this, inspired by James Tanton.

Made fruitcake from an old recipe that makes one large (8x8), one medium (6x6) and one small (4x4) cake. How would you turn this into a math problem? #mtbos #iteachmath

I love reading the small details about how Marilyn launched and facilitated the task! #ITeachMath ♾️

And I must protest the statement in the "Integrating AI into the Arts" lesson that "Digital tools are 'green,' making them environmentally friendly from a climate justice and sustainability perspective". They may be inclusive but they are not environmentally friendly. earth.org/the-green-di...

This is the coolest, strangest thing you will watch (and likely re-watch over and over) today

Applications of simultaneous equations might be my favourite topic. There are just so many fun problem types! We did these Don Steward beauties in Y10 #MathsToday.

Q1: I drew some polygons on dot paper. I labeled each with 3 numbers. What do you notice and wonder? #ElemMathChat

Q6: How many stickers could there be in the bag? #ElemMathChat

It’s 2025. Why? Just why? #iTeachMath

How did this not make The Stanchies, @stanch.bsky.social? Highlight of my #Canucks viewing experience. @canucksarmy.bsky.social

12 years after his first appearance, Sal Khan was back on 60 Minutes to talk AI. And I have thoughts 2ndbreakfast.audreywatters.com/12-years-and...

Ahhh thank goodness, @ddmeyer.bsky.social watched 60 Minutes go back to the Hype Well for Sal Khan so I don't have to. What's it gonna take for folks to stop listening to someone who's been so consistently wrong about the future of education? (Sal, not Dan) danmeyer.substack.com/p/five-inter...

Another great piece from @ddmeyer.bsky.social. This one skewers Sal Khan and Khan Academy. I love this critical thinking and pushback against a millionaire trying to shape public education. #EduSky danmeyer.substack.com/p/five-inter...

People are right now slobbering pretty hard over this AI tutor demo over on LinkedIn. I think it's a mess—pedagogically, socially, and mathematically. What do you notice?

The BC MoE developed AI-related teaching and learning examples in various grades and areas of learning. Thoughts on the Math 9 one? www2.gov.bc.ca/gov/content/...

@natbanting.bsky.social I don't know if these count as #turdmath or if it's me I'm the problem. I watched this one. I know Hughes had a helluva game. But purple and teal, some going left, some right... negative team offence (for individuals) above average?! I don't get it.

"Vertical drop, horizontal tug" is my new "rise over run"

natbanting.com/rip-bos-a-tr... New Blog Post. (it's been a while) A reflection on the MTBoS, what it's meant to me, and how--on it's deathbed--it helped a student in a big way. #iteachmath
