We used to do the #tapediagramtuesdays in our office to practice! We stopped but should start again! #elemmathchat

Courtney Flessner @cfless.bsky.social · 02/10/2026

Couldn’t help but to post a behind the scenes of this month’s #elemmathchat with @ryanflessner.bsky.social because when else will that be possible?

YES! oh how I love those moments for teachers and kids! #elemmathchat

Courtney Flessner @cfless.bsky.social · 02/10/2026

Yes! Just today I was working with elementary teachers doing work like this. Jaws were literally dropping. It’s such a shame how many people in our world don’t know how you can work with numbers to help computing them make more sense and be more efficient. #elemmathchat

Courtney Flessner @cfless.bsky.social · 02/10/2026

It’s literally amazing what you can do with the simplest moves and flexibility with numbers. I’m still working on training myself to think this way at so many things. #elemmathchat

I mean it was firm criteria. That and loving baseball.

Courtney Flessner @cfless.bsky.social · 02/10/2026

Yes! I love pointing out favorite numbers in different places. For example, my favorite number is 8. For years and years. And then one day I realized I had 8 letters in my name, my last name, and my maiden name and I had literally never made that connection! 8 was meant to be my fave number maybe?🤷🏼‍♀️

Courtney Flessner @cfless.bsky.social · 02/10/2026

After “taking apart numbers and putting them back together” I would add “so you can use them flexibly.” I think many teachers think if they teach students how to take numbers apart and put them back they have number sense. Isolating number sense ideas is a common issue I see. #elemmathchat

I like to encourage teachers to use whatever worksheets that have found as a starting point. I write a whole blog post on this once. I should find it!

Courtney Flessner @cfless.bsky.social · 30/01/2026

Hi! I always think about encouraging teachers to use the practice task to apply with a nudge. Like what can the task do to move them forward a little and *use* what they learned rather than practice what they learned?

Calling all educators! Speaking at #KINLCon is such a rewarding way to grow professionally and give back to the education community. I’d love to see your session on the schedule this year! 🌟 Propose now to speak: KeepIndianaLearing.org/KINLCon

I kind of want to look at the teachers and say, “I can’t fake this. I’m too tired to gather up that kind of energy!”

Courtney Flessner @cfless.bsky.social · 07/11/2025

I even had kids over the years where I’d say, “Thursday! Thursday is going to be YOUR day!” I always giggled to myself but sure enough they were ready on Thursday!

020

Courtney Flessner @cfless.bsky.social · 07/11/2025

It’s so true! And the key is genuine. I sometimes wonder if kids thinking I’m faking how excited I am to talk to them about their thinking. I actually never am. More! Tell me more!

230

Courtney Flessner @cfless.bsky.social · 07/11/2025

For the particularly shy ones I warn them. I may say, “Today I’m going to make sure you have a chance to share your awesome math thinking with everyone.” It gives them a chance to pump themselves up because they know it’s coming. I’ll make eye contact in advance so they know it’s coming:)

120

Courtney Flessner @cfless.bsky.social · 07/11/2025

When I’m talking to a student 1:1 I say, “Tell me about your mathematical thinking…” I use other prompts like, “Tell me more about…” Before asked questions to move forward learning I might say, “What I heard you say was…am I describing your thinking correctly?”

020

Courtney Flessner @cfless.bsky.social · 07/11/2025

Or when they might even know it’s inaccurate because they struggled so much but you point out something they did well first, they believe they can do even more!

I was just in a first year teachers classroom and it was delightful to see that it didn’t look like Pinterest had thrown up in her room. The environment was all about the students and their work. I absolutely love this fact!

020

Courtney Flessner @cfless.bsky.social · 24/08/2025

I love how when I show teachers a photo like this they ask, “How many can you see or how many are there? Are we counting the total or how many of each?”etc. When I don’t have a straight answer, and they find themselves counting both ways, I get - “I see what you did there.” 💚 images like this one.

Thanks to the #BTCC25 planning committee for trusting @cfless.bsky.social and me with microphones! It was amazing to emcee the opening session, to get everyone up and dancing, and to hear @pamseda1.bsky.social’s keynote. Can’t wait for tomorrow’s closing session!
