Had an extra day with one class compared to others today, so we tried out a @mathforlove.bsky.social activity “Squarable Numbers”. Had 100% participation and lots of good discussion. #iTeachMath #MTBoS mathforlove.com/lesson/squar...

I’m staring at this chair in a waiting room. The more I look at it, the more it’s making me feel agitated. Is it just me? #mtbos #iteachmath

Math + Mom + Books + Life: I really am a Desmos Fellow! mathmomlife.blogspot.com/2025/07/i-re... #mtbos #iteachmath #mathchat #desmos

I was baking cupcakes with the 6 yo and (of course) did fraction work with her. I got out the 1, 1/2, and 1/4 cup measures and asked her questions about them, had her read the symbols, etc. I told her we needed 3/4 cup of sugar and asked her how we should do it.

Playing Mastermind with my 6 year old inspired me to make this in #Desmos. I discovered I'm a lot worse at guessing than I thought! #MTBoS #iteachmath classroom.amplify.com/activity/687...

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

My new favorite method for practicing #French: I read Percy Jackson in French and translate out loud to English in real time as my 10 yo follows along in the English text and corrects me as I go. I mean the first chapter is about vaporizing his math teacher by accident so we’re off to a good start!

Math friends - Amplify Desmos Math has just opened up applications for their next group of Fellows. Being a Desmos Fellow has been the best PD I have done in 25 years. It’s an incredible community. Please consider applying! #mtbos #ITeachMath amplify.com/desmos-fello...

A revelation that hit me during my conversation w/ @pernille.bsky.social is the tension & pressure of training American teachers to be superheroes needed to rescue kids from failing economic systems while ignoring those systemic failures. The demand to be superhuman is ultimately dehumanizing.

Rights of Learners! Conversation between Olga Torres, Crystal Craig, & Priya Prasad: "It’s not that one person has better thinking than the other. It’s that everyone has different ways of thinking or viewpoints that create the opportunity to reflect [& revise]." www.tandfonline.com/doi/full/10....

I wanted to share a few student work examples of the Math Language Routine #StrongerAndClearer that show how much of an improvement there can be without the teacher giving any feedback, from both language learners and English fluent students. bit.ly/4f92vJN #UDL #iTeachMath #MTBoS #edusky

I handed out a copy of hand-written worked solutions for a task. Student quietly to a friend: "what kind of name is 'Exemplar'?!" 😂 #iteachmath #mtbos

I’m so going to use this for Shuffle Quizzes. #complexinstruction ♾️ apps.apple.com/us/app/chwaz...

We're hiring an Accessibility Specialist on the Amplify Desmos Math 6-12 team! If you're interested in making the curriculum accessible for all students, please consider applying! amplify.wd1.myworkdayjobs.com/en-US/Amplif... #desmosclassroom #iteachmath

What I don't understand is how the United States spends 154 hours on math instruction each year, 20hrs more than the international avg, & 40hrs more than high scoring EU countries like Finland & England. In fact, you'd think there was an inverse correlation between instructional time and outcome. 😵‍💫

In #mathstoday we reviewed Pythagorean Theorem. I used a #desmos activity that worked pretty well. I started with two proof without words puzzles adapted from @mathtechcoach.bsky.social as a way to ground it visually and built from there. teacher.desmos.com/activitybuil... #iTeachMath #MTBoS

Wow, the mathematical thinking that my little guy is doing while staying up late organizing his baseball cards into various categories is really fun to watch. He just reasoned his way into locating his missing Juan Soto. #tmwyk

I just made a #Zukei puzzle template with correctness check in #desmos. It's fairly easy to create additional problems with it. I'll use some puzzles like this in next week's coordinate geo unit. #MTBoS #iteachmath ♾️ teacher.desmos.com/activitybuil...

I just created Blue Sky accounts for Open Middle (@openmiddle.bsky.social) and Grassroots Workshops (@grassrootsws.bsky.social). My hope is to start sharing a lot more content on this platform, so please give these accounts a follow.

When I moved to CA years ago, I lived in San Jose, and through all the people I met and the work that I did, my world view expanded exponentially. #ManuChao ‘s Clandestino always brings me right back to that time. I’m happy he’s released a new album after 17 years! music.apple.com/us/album/viv...

Does anyone know if you can combine individual #feeds into a single aggregate feed in #bluesky?

This was the perfect listen for driving home calmly in the rain. music.apple.com/us/album/fee...

I want to share the #desmos fellows project I put together earlier this year. It's a 3-part sequence that moves from adding lines visually to making sign charts of factored polynomial functions. bit.ly/411q18q #MTBoS #iteachmath ♾️

Oh no my 8 year old just developed a liking for my Spindrifts.

It’s kind of nice talking about elementary math ideas while cooking dinner. ♾️

Well it was raining and lots of kids are sick. I had like 35% of students absent today. Between that and my first activity taking twice as long as expected, gotta try this again next week 🤣

At a PD today, we examined the principles behind the Math Language Routines (such as Stronger & Clearer and 3 Reads). 1) Support sense-making 2) Optimize output 3) Cultivate conversation 4) Maximize linguistic & cognitive meta-awareness It's a great resource! #MTBoS #iteachmath stanford.io/3Zfua78

Here's a linear programming activity I've been iterating on in #desmos. It's intended as a scaffold for students to practice writing inequalities and the profit function to model the situation. It's a challenge to fit it all onto one screen. ♾️ #MTBoS #iteachmath teacher.desmos.com/activitybuil...

I wrote two books for teachers, Equity-Centered Trauma-Informed Education and Becoming an Everyday Changemaker. Both are written to help teachers transform schools into communities where everyone feels safe and cared for. 💜💕

#MTBoS This is a great resource to help all students see themselves as mathematicians. Very powerful stories. maa.org/wp-content/u...

"A negative and a negative is positive." Is that always, sometimes, or never true? I used this #desmos activity to help my students visualize how negatives work with each operation. ♾️ #iTeachMath #MTBoS teacher.desmos.com/activitybuil...

I wanted to share this Master's thesis written by Ethan Merlin (who I've never been able to locate to properly express my appreciation!). ♾️ #MTBoS #iteachmath #mathsky A 🧵 👇 drive.google.com/file/d/15Tq-...

I was going to delete my #twitter account, but it seems that there is nothing to stop someone from making a new account with your username. I've seen people say they've deleted their accounts... are you worried about this, or is there a way to prevent it?

I didn’t realize at first that this book would be told from the perspective of a neurodivergent narrator. It’s a character study where not much “plot” happens and seems kind of dark at first, but is really warm-hearted, satisfying, and funny. www.simonandschuster.com/books/Intere... #BookSky 💙📚

I'm working on graphing linear inequalities now. I've needed to emphasize the graph-algebra connection. I started with only non-strict problems for a couple days. Then I introduced the idea of the dashed boundary line with this sequence. I thought it worked well! (see presenter notes) bit.ly/40E47YF

When I first learned this CII strategy, the incomplete came *before* the incorrect. I also asked detailed questions on the sheet instead of open-ended conversation. I'm wondering what people think about these differences? Do you prefer one version over the other? docs.google.com/presentation...

I started listening to #animalcollective and #pandabear a few months ago and it has been saving my sanity. Listening to Tomboy for the first time now - it’s physically soothing my ears and I can feel my entire nervous system calming. music.apple.com/us/album/tom...

Ohio Jones...I made this many years ago after a particularly hard time in my life. This was a part of trying to get myself back on track again. I think about that every time I use this, and it's that time of year again. drive.google.com/file/d/17xd6...

Teachers: you had your students for 2 to 3 months. Today might be a good day to look at your rosters and make sure you can name a strength for every single student. #iteachmath #edusky

I've been making CII (Correct, Incorrect, Incomplete) tasks to deepen students' understanding of particular topics. First, they discuss the Correct work in groups and I ask them questions. They do the Incorrect column and we debrief, then they finish the Incomplete. #MTBoS #iteachmath bit.ly/3YXGpW2

Why is it so adorable when my 5 year old calls New York “Yew Nork”?

For spirit day tomorrow my kid is supposed to dress up “like a photographer”??

Sharing music with my 5 year old. Singing along the “na na na na”s (Hey Jude). She smiles at me and says “Daddy, you have terrible singing! They are much better. Why?” 😊

The irony of leaving SF for NYC, only to experience an earthquake here!

Here's a #DesmosClassroom template for graphing transformations of parent functions. #Desmos #MTBoS #ITeachMath teacher.desmos.com/activitybuil...

I'm happy to be joining the #desmos fellows this summer in Denver! Here are some congruent triangles to celebrate :) teacher.desmos.com/activitybuil... #MTBoS #ITeachMath #EduSky
