In this Feature (9-12) article, authors share how historically marginalized ninth-grade students in Ontario used budgeting activities to explore not only pay stubs and deductions, but also questions of equity, government spending, and social justice. 🔒NCTM Member exclusive: nctm.link/G9mPX

#ITeachMath #MathEd can anyone help me find the article or other resources where students (or preservice teachers) can chart their mathematical autobiographies using a line graph as a way to think through their histories as math learners? I know I have seen this, and cannot find it!

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

I wrote up an experience using a slow reveal graph with a fourth grade class for Edutopia. ✨

A wonderful learning day in PSSD about Spiraling Your Math Curriculum. Always happy to have access to @wipebook.bsky.social for our thinking tasks & collaboration time! @pstateachers.bsky.social

This blog post, by Ian Maurer is a quick and easy read about how extensions can really make a task sing (or chirp). This blog post reminds me that a stories task can start off simple and with the right perspective, can make the mathematics very deep and complex. imaurer.weebly.com/blog/when-bi...

Have foreign tourists really avoided America this year? (2025) Have foreign tourists really avoided America this summer? This graph from the Economist may look like a simple bar graph, but it asks the viewer to integrate ideas about both percentage change and also the actual change.

Happy September, happy new school year, and happy #ProblemSolving calendar! Share your thinking (& your students' thinking) here or on the post. #MTBoS #iTeachMath #T3Learns #RecreationalMath #MathSky #MathsToday karendcampe.wordpress.com/2025/09/01/s...

Any old #bcedchat folks have a lead on a veteran math history teacher??

With all sincerity, Elections Canada is a national treasure. - Voting typically takes less than 15 minutes - We make it easy for citizens to vote, without cumbersome registration hurdles - We have every reason to trust that ballots will be counted fairly, and results reported swiftly

First attempt #smudgedmath decimal division

One of my absolutely favourite tasks from @peterliljedahl.bsky.social

@triangleman.bsky.social for #vehiclechat, or maybe @jennalaib.bsky.social#vehiclechatfor a slow reveal graph

Hi friends! I have a book coming out next month! It is full of *gorgeous* photos such as seen on the cover here. There is one really fun photo that didn't make it into the book...

I made this for a friend who was headed off to talk with first graders about circles last week. Which one doesn't belong?

So many terrific tidbits and ideas in here. Thanks, as always, JoAnn!! #iTeachMath

I’ve read this Teacher Guide (some chapters twice) It’s everything you expect from Christopher—curious, technical, and beautiful.

Good morning! Number one way in the coming weeks to support the work that brought you Which One Doesn't Belong?, Tiling Turtles, Math On-A-Stick, and the Hierarchy of Hexagons is this: Pop into your fave bookstore or library to ask for How Did You Count? ISBN: 978-1032898353 Coming in March

I finally had a chance to read this post. So much learning here, for me as a T & for the lucky learners in this classroom Worth the read! ⤵️ #iTeachMath

This makes me think of the terrific structure @triangleman.bsky.social shared at #NWmath2024 and the ‘edge case’ when creating definitions @bcamt.bsky.social

Made a Starter Pack of *current* K-12 math classroom teachers. Let me know if you should be added (or removed). go.bsky.app/35M7izP

@gkelemanik.bsky.social I’m so excited to see you here! 💛

Visited Grade 1 again today. We talked about the equals sign meaning basically 'is the same as' and made shapes that were the same as each other different ways. #patternblocks

Kindergarten #MathPlay 🧮 with Maddie👨‍👧 - We created our own concept circles ⭕️🔢 #ITeachMath #MTBoS #STEM #ElemMathChat #MathIsFun #EduSky #MathChat

Two new #MenuMath added to the site. One on factoring polynomials from Michael Roberts Another (pretty spicy) one on geometry on the plane from Alli Etherington natbanting.com/menu-math/ #iteachmath

Please let the other group members from the old place know that they can find us here in the Blue Sky Ballroom.

The February Calendar of Problems is here! Enjoy #ProblemSolving this month. karendcampe.wordpress.com/2024/02/01/f... #MTBoS #iTeachMath #MathSky

Hello Bluesky! Please welcome my new workplace @mathhappens.bsky.social to this space. We've got some super fun stuff already going on, and in the works for the new year!

Will never regret doing a Choice Board for the last assessment of the semester 👏🏻 it’s saving my sanity this week and the students get a choice in how they show their learning!
