Giving away our secret PD sauce :) My NEW post: Building a PD Program for Mathematics Teachers & Coaches fawnnguyen.substack.com/p/building-a...

Just got Math Decoded by James Tanton and I'm so happy. 📚✨ It's pure James—accessible, joyful, with colorful sketches that are exactly what you need, right when you need them. You can hear his voice on every page, kapows and all. So, so good. www.corwin.com/books/math-d...

#unitchat When airlines use "minutes" to describe the delay.

I can't afford first class, but I prefer the exit row for my long legs. And when the flight attendant asks, "Are you willing and able to perform emergency duties...," I respond with a firm yes. This is a lie. My yes just means that I'm ready to die with the rest of y'all.

I've been making a lot of soups lately. Has anyone done a blind taste test (like Pepsi vs Coke) to pick out the soup cooked with bay leaf vs. one without?

Happy Wednesday, everyone! I hope your winter break is just around the corner, and a good book 📚 or hot beverage ☕ is in your near future. Quick share of my new post: Finding the Smallest Sum open.substack.com/pub/fawnnguy...

#ElemMathChat A4 Most recent re-learning was at NCTM and @fawnnguyen.substack.com session using Visual Patterns. I have been working with teachers and after my session of using Visual Patterns they all wanted www.visualpatterns.org and more on making connections. ❤️ Spreading the love of #Mathing.

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

It was an amazing experience. Your care, compassion, and sense of humor made the experience so memorable. Thank you!

Another example (that’s more complicated) These are just warm ups- the key is SEEING the patterns visually (Avoid bringing in tables in this warm up activity) #Math @fawnnguyen.substack.com

Look what arrived! Just when you thought the K-5 book was big, the 6-12 is even thicker! I've been through it already and wow—peterliljedahl.bsky.social and @webbkyle.bsky.social really delivered. You want this. 🔥

Happy Friday! I just tried all these fun activities that you can customize! Check out our collection of free fall activities at #AmplifyClassroom! Students estimate quantities of candy in a jar, carve pumpkins, decorate their own fall scene, and more! classroom.amplify.com/collection/6...

We now officially have 500 visual patterns! 🎉 Christophe from France just shared SIX wonderful building-brick patterns he discovered while playing with his daughter. 💕 Check out visual patterns #495-500: visualpatterns.org/451-through-...

Really loved this episode! "Kids in math class can have different answers that are right and that they can be wrong in a smart way." @ddmeyer.bsky.social joined Anayansi (Ana) Torres on the latest episode of Beyond My Years from Amplify. podcasts.apple.com/us/podcast/t...

Don had such an amazing eye for a rich problem, that he always then turned into a rich, connected set of problems.

Love this post Fawn, especially this. Hope you got a good nights sleep!! #iTeachMath

Tried this problem with my math club today - they’re a group of 6th and 7th graders. They solved it in ~25 minutes. Take that, AI! lol. #ITeachMath #MTBoS

Also wanted to start strong on Thinking Classrooms (@pgliljedahl.bsky.social) work after some struggles last year. Very grateful for @fawnnguyen.substack.com's piece on giving yourself permission to go off-script. Kids especially enjoyed the Chicken Nugget Task and showed so much thinking! 3/3

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!

Sophia (gr. 6) worked with VisualPatterns.org and wrote quirky and neat stories about each of her own two-color growing patterns. She also obtained recursive and closed formulas. Happy upcoming #MathStorytellingDay to @fawnnguyen.substack.com! naturalmath.com/2025/04/a-he... #iTeachMath #MathSky

Pullback cars must mean it’s time for Vroom Vroom ala @fawnnguyen.substack.com . Reviewing linear regressions was never so fun. #iTeachMath #Algebra2

Check out how Mr. Stadel starts Day 1 (you can start this on Day 16; it's never too late). Love the setup to begin a "low-risk high-trust" math class!

A slightly different questions is 'What is your favourite math(s) problem?' I really enjoyed reading some of the answers shared by @fawnnguyen.substack.com in this post: fawnnguyen.substack.com/p/hudson-hawk

This is an excellent piece, but... Fawn's Wolves and Sheep puzzle (linked to in the first sentence) is vexing me. I'm very vexed.

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...

I put a lot of these kinds of problems (though not this particular one, obviously, since it was new to me) in our supplemental curriculum. I don't know if supplemental curricula are always the way to go, but there are advantages to having something you can add in anywhere. mathforlove.com/curriculum
