7 ESSENTIALS TO ENSURE A CULTURE OF BELONGING. “You are welcome here.” It’s the message every student longs to hear as they walk through a classroom door for the 1st time. #edusky #T2Tchat @larryferlazzo.bsky.social @sharemylesson.bsky.social @amleorg.bsky.social www.middleweb.com/52524/7-esse...

New blog post! "Find Your (Math) People" -- about the vitally important connections we make w/other teachers. Be a buddy, find your groups, and carry on the legacy of @druinok.bsky.social who left us too soon. #MTBoS #iTeachMath #T3Learns #ForShelli karendcampe.wordpress.com/2025/08/05/f...

Excited to share my recent article published on @edutopia.org! It doesn't take much to start to shift practice towards a more shared culture of teaching and learning in our math classrooms. #MTBOS #elemmathchat #iteachmath #edusky #mathsky www.edutopia.org/article/stud...

I'm presenting at ATMNE in the fall! "Shifting Practice: Creating a Shared Culture of Math Learning in Your Classroom" on Friday 10/31 at 10:45. Register at atmim.wildapricot.org/event-5937758. #ATMNE25 #ITeachMath #MTBoS #ElemMathChat

Saw this on FB and thought it would make a good math warm-up or Math Talk What would you pick? 🍫🔥

🚨 Emergency scripts. 📝 Classroom contracts. 🎯 Modeled expectations. These teacher-tested techniques take a proactive approach to classroom management. #ClassroomManagement #EduSky

When something goes wrong in class, collective punishment probably isn’t the answer, says educator Matthew Ebert. But if you head down that path, there’s still a way to come back and build trust with students. Here’s how. 👇 #ClassroomManagement #EduSky

Looking forward to this one! #OAME25

In case you haven’t lately, survey your students. I always forget how much valuable input students are willing to give when you give them the chance!

Not enough people are paying attention to the multiple levels at which eliminating the Department of Education works to advance a bad agenda. As a sociologist, I'm seeing some things are worth your attention as you argue about the role of EdGov in our students' lives: (1/6) 🧵

“KiDs tHeSe days: Can’t tell time Don’t know coins” Reminder that *adults* created the digital clocks & payments. Kids are living in the world adults created. If they only see an analog clock and coins in math class it’s harder to learn! Not that it’s not important but let’s stop blaming the kids.

Win Puzzle Club about Artful Knots. Ss explored knot designs from India and Ireland, learned to draw that 'S' knot that I drew on my notebooks in middle school in the 90s, and tried some Loop-de-loops from This is Not a Math(s) Book. #iteachmath #mtbos docs.google.com/presentation...

For anyone leading, facilitating, taking part in a curriculum review and adoption process, this is a great read. Instead of fidelity, this: "The curriculum sets the bar, and teachers use their professional judgment to supplement and adjust so that students can meet that bar."

In my 15 years working with districts to help make high school mathematics JOYFUL, MEANINGFUL, and EQUITABLE, I have found quality curriculum can have a tremendous impact. So, I've been working to make such curriculum freely available: www.math-that-matters.com #mtbos #iteachmath #edusky

Two more same & different: This time looking at the structure of multiplication and division. #mtbos #desmosclassroom @looneymath.bsky.social

I love using the "Same & Different" routine for examining student work. Here are three we used back to back today to highlight features of graphs, including neatness, scale, indep/dep variables. #mtbos @illustratemath.bsky.social @looneymath.bsky.social

I love this paragraph from @dylanpkane.bsky.social's post about conceptual learning. One of my big criticisms of the IM curriculum is that they don't smear topics over 1-2 weeks like this. Smearing is better! #iteachmath #mtbos fivetwelvethirteen.substack.com/p/conceptual...

Note to self: This year I gave the 1-100 sheet (in past I started with 1-20 or 1-50) and noticed fewer students digging in. I think 1-100 was overwhelming. Next year, I'll give 1-30 and expand once we get going. First impressions matter in math puzzling too! #mtbos @mathequalslove.bsky.social

Chip Trading: 1 game ♾️ levels: 1 - base-10 blocks, trading 10s; 2 - colored chips, trading 10s; 3 - colored chips, trading 3s, 7s; 4 - adding/subtracting with 3s 7s. Ss play/explore the same idea (trading) and answer the same questions with diff levels of sophistication. #mtbos #elemmathchat

Quicksand! 💯

Happy 2025! If you're looking for some math-y fun today (or for when your students return to the classroom), check out the 2025 Yearly Number Challenge! mathequalslove.net/yearly-numbe... #mtbos #iteachmath #puzzlingclassroom #mathsky #edusky #math

The 2025 Game: arrange the digits 2, 0, 2 and 5 with symbols in between (e.g. +, -, ×, ÷, ^, !, etc.) to make the numbers 0-10. For example, 2+0+2+5=9. How many can you make? (I just confirmed all numbers 0-10 are possible.) #MathsSky #MathSky #MathsToday #MathChat

I feel defeated. Because it feels like all of my planning time is spent anticipating how to manage my classes, not actually planning to do good math teaching. So today I taught poorly. I know I can do better, and yet today I did not. Today it felt like too much. I'll try again tomorrow. #mtbos

One thing I appreciate about the #iteachmath community is that often by reading through your collective thinking, I get answers to questions I didn't realize I had. 🙏🏻

I wrote about how I use the @desmos.com data collection screen for a Fermi problem routine in my classroom www.edutopia.org/article/tips... and here is my Desmos collection of those screens: teacher.desmos.com/collection/6... Any other Fermi problem fans in the #mtbos #iteachmath ♾️ community?

I really love this 3 act math task! (related to your comment @johngolden.bsky.social) kristenacosta.com/divided-hear...

I really appreciate this commentary from Chuck Munter: "The myth(s) of the 'balanced' approach" to mathematics teaching #iteachmath #mtbos kappanonline.org/the-myths-of...

All this is not to say that schooling is not important or effective for math instruction but that the United States is socioeconomically distinct from our OECD peers, where our child poverty rates look more like Italy, Bulgaria, Spain, and Mexico and far less like Denmark, Norway, & Finland.

#learninglabs Session 2 with gr 4 & 5 Ts: Spent time co-planning gr 5 number string. What a treat to dig into teacher moves, anticipate student thinking, and practice setting and teaching towards learning goals. And, Ts role playing "tricky" Ss offered a much needed laugh to end the day. #iteachmath

I used this activity with an elementary class this week! Students loved it! m.youtube.com/watch?v=VGnD... #iteachmath #math #mtbos

In #MathsToday with Year 8, we discussed how to determine if we were tipping enough after a restaurant meal and the process for calculating it. Here is a lesson resource: mathswhiteboard.com/MWB/lessonpl... To create more lessons: mathswhiteboard.com/MWB/lessonde... #maths #mathschat #iteachmaths

As a follow up to this Dot Puzzles. I was thinking about how we can use this same set up with fractions in 3rd Grade. Here's a very rough mock up of a puzzle format: #iTeachMath #MTBoS #mathstoday

What's the fairest way to tip? A great #RealWorldMath 🌎 debate using percents, decimals operations, and some reasoning with the distributive property. youtu.be/0gaaxK98M78?... #iTeachMath #EduSky #MathSky

🙌 “When you create a mathematical model, it doesn’t matter how beautifully crafted your equations are, or how accurate your simulations are...You have to think about how the work is going to be seen and perceived by other people and how it’s going to be understood or misunderstood.” #RealWorldMath 💎

Another amazing resource. Thank you, Tim!

I love this phrasing. I said before that we study the past to inform our decisions and understanding of the present. Every artifact tells a story. Students of today can be the authors of the math ideas we explore in the future. #mtbos

Some dissection puzzles I made four years ago #math #puzzle #iTeachMath

Played a game of Number Boxes (jennalaib.com/2019/05/29/o...) today with 6th grade. Ended up with these two equations with 30 seconds of class left. "But why ARE the values two apart???" 🤔 (Don't worry 6th graders, we'll definitely revisit this gem next class 😉)

I love sharing this with students every year. I have it in my Google Calendar.
