So proud of @cfless.bsky.social who was chosen to speak at @nctm.org’s Leasership Summit. #rockstar

Who has students who volunteer at a conference at 7am on their day off! 🙋🏻‍♂️ Proud to have @skuchler.bsky.social @elliewells-gr.bsky.social @taylorbyrd.bsky.social @emilyg03.bsky.social @sfrancesconi05.bsky.social & @andrea-curtis.bsky.social representing the @butleru.bsky.social College of Education!

Welcome to Indy! After my presentation tomorrow morning (8am), I’ll be hanging out at the volunteer table in the Expo Hall for most of the day.

When the kids start #mathing without even knowing they’re mathing. How many? #howmany

Thank you, @sueoconnell.bsky.social, for facilitating tonight’s #elemmathchat! It’s always fun to be with this crew. @mfannie.bsky.social - hope you arrived home safely. I’m looking forward to your responses to these ideas!

A9: I love answers kids give to questions like: What made you feel confident/powerful today? What was frustrating? What’s one thing you learned? Who taught you something important today? What are you wondering about the math? Or - just tell me what you’re thinking about math today! #elemmathchat

Routines, routines, routines! If we want kids to do math, we have to hold them accountable to doing the math!Let’s put routines in place that encourage them to do the math, talk about the math, and document the math.

@sueoconnell.bsky.social - Your ability to facilitate this chat is amazing! How are you responding to everyone, posting questions, adding additional ideas…?! I’m just trying to keep up! #elemmathchat

A6: I’d give kids choices of dice (d4, d6, d8, d10, d12) and ask them to work with their partners to pick just right dice. I love talking to kids about the dice they’ve chosen, how the different dice impact the work, etc.

A4: Task on left provides a visual model and the ability for all players to verify one another’s thinking. Task on right doesn’t ask students to discuss/display their thinking. Task on left seems to encourage automaticity; task on right could easily promote memorization. #elemmathchat

A2: I used to think worksheets were useless. Now, I try to find ways to learn about kids if I use them. I ask students to pick 3 problems that feel just right to them. I learn a lot about kids through their choices. It’s fun to talk to them about *why* they made the choices they did. #elemmathchat

A2: I’ve seen a lot of people starting to offer fact fluency games as options. Let’s get kids and their loved ones laughing and having fun together instead of fighting over algorithms that are unfamiliar. Let’s build bridges, not burn them!

I’m Ryan. I’m a professor at Butler University in Indianapolis. Thanks, @mnmmath.bsky.social, for organizing. Thanks, @sueoconnell.bsky.social, for leading tonight! #elemmathchat

New episode What if you don’t understand your student’s math strategy? We talk with Ryan Flessner about how educators can respond in ways that support student learning and mathematical identity. Listen now: www.mathlearningcenter.org/blog/ryan-fl...

Fabulous conversation with Ryan Flessner! Big Idea: How we respond in the moment when we don't understand a student's thinking matters! #iteachmath podcasts.apple.com/us/podcast/r...

Thanks for hosting #ElemMathChat again, @mnmmath.bsky.social. I appreciate the space you e created for all of us and your flexibility in ensuring we all stay connected!

A1: Im not in K-12 anymore. As a teacher educator, things look quite different. I’m going to learn from all of you tonight! #ProgressMonitoring #ElemMathChat

I’m Ryan, a math teacher educator from Indiana. I’m a bit late to the party, but I’m happy to be here for #ElemMathChat! Happy New Year, everyone!

Are you ready?! It's almost that time. #MathIsFigureOutAble #MTBoS #ITeachMath #MathEd

Hi #ElemMathChat! Ryan Flessner from Indiana. I’m a teacher educator, and I spend as much time as I can hanging out in schools with teachers and students who teach me so much!

Winner of tonight’s “most succinct post PACKED with ideas” award. #ElemMathChat

Yes! Connecting - one of the 5 practices. So important. I feel like this is an area of growth for me. #ElemMathChat

Hey fellow #ElemMathChat peeps - We’re trending!

Yes! We have to do what we want our students to do! So powerful! Part of growth mindest learning is vulnurabilitiy learning! At the end of Unit zero I share this quote - on my vision board- every year! #ElemMathChat

A1: Start by having routines from the beginning of the school year where exploring and conjecturing and asking questions are built into the math. That way, sharing ideas as they form is just part of the culture of learning. #ElemMathChat

The Math and Other Things podcast is back! I’m a big fan of the episodes (and people in them) that have dropped. Special thanks to @ryanflessner.bsky.social, @rob-baier.bsky.social, @cluzniak.bsky.social, and @themathguru.bsky.social for amazing conversations! podcasts.apple.com/us/podcast/m...

Fun surprise to start my day: @kimmontague.bsky.social mentioned my #NCTMATL25 session on the “Math is Figure•out•able” podcast! Can’t wait to work with @pwharris.bsky.social as we continue to convince Kim to join #teampen 😊 Check out their podcast here: podcasts.apple.com/us/podcast/m...
