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...

Looking forward to NCSM in Atlanta! Hope to see you there! It'll be my first time sharing "Building a PD Program for Mathematics Teachers & Coaches" Tuesday, October 14, 2:15 p.m. - 3:15 p.m. - International Salon 9

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!

NEW Post: My 7th Graders Are Better Than Yours :) fawnnguyen.substack.com/p/my-7th-gra...

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 post: Hudson Hawk (What is your favorite math problem?) fawnnguyen.substack.com/p/hudson-hawk Thank you for filling out the survey and I shared the responses.

NEW post: The Illusion of Thinking fawnnguyen.substack.com/p/the-illusi...

Hi Everyone, I hope you can help me answer an anonymous, SHORT 2-question survey: forms.gle/Ri58V4oSEyeR... Thank you in advance! 🙏❤️

NEW post: Cracking the Strategy, when a 4th grader explains her thinking fawnnguyen.substack.com/p/cracking-t...

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

NEW Post: Lines and Squares fawnnguyen.substack.com/p/lines-and-... One of my favorite tasks. Well, they all are.

NEW episode of Beyond My Years is out today—and somehow I got invited back 😅 Grateful to chat w/ the ever-thoughtful Ana Torres + hear from the amazing Rebecka Peterson & Simone McQuaige. We talk early teaching struggles. 🎧 amplify.com/beyond-my-ye... @amplifyeducation.bsky.social

Probably my favorite theorem, and such an amazing exploration. Sometimes I'll launch with a magic act, of tell me your count and I'll tell you your area.

What a wonderful lesson. Take a moment to read Fawn’s post. #iTeachMath

This was a delight to read 💕 It made me want 2 things: 1️⃣ to be back in 4th grade 2️⃣ to be in Fawn’s class fawnnguyen.substack.com/p/dot-paper-task #iTeachMath #mtbos @fawnnguyen.substack.com
