Collaboration in our classrooms shapes who talks, whose ideas are taken up, and the depth of understanding that emerges. I just posted part two of my adaptation series focused on structuring small group work: kgmathminds.com/2025/11/28/ada…


Adapting lessons is probably one of my favorite problem solving activities as a teacher. I love the design challenge of ensuring the adaptations support students in accessing and meaningfully engaging with that math while addressing the learning goal. kgmathminds.com/2025/11/25/ada…


If my years watching (and rewatching) Glee! taught me anything it is that I can't resist a good mashup! 🎶 So when @jennalaib shared her latest Slow Reveal Graph, I had to combine two of my favorite math activity structures. #mtbos kgmathminds.com/2025/11/23/slo…

Unsure if any of the #mtbos folks are here anymore, but I am dusting off the blog and excited to be writing again! kgmathminds.com/2025/11/22/for…


Teacher friends....which do you find is most challenging to teach? Would love to hear what makes it hard in the comments! #mtbos #mathteaching

The first deck in Addition and Subtraction by Heart II focuses on adding within 20 and uses 10 frames as the visual representation. For the first few times students see a card, they can move around the counters. Learn more at fluency.amplify.com


Sooo much fun working through this problem! Thanks Zak!

I created this immersive math task for our math play date last week. You can download it at bit.ly/ShuffleArt. Enjoy! #math #matheducation #mathclass #theshuffle

Deck 6, the final deck of Addition and Subtraction by Heart 1, uses number bars to provide the most abstract representation of subtracting within 10. Try for yourself and learn more about the free fluency practice resource at fluency.amplify.com

Reviewing for tests can be challenging to structure because students make connections in different ways. When I saw this idea on IG, I was so excited to try it out & then drag my amazing colleague @CoachPMath into a Reel! instagram.com/p/DBrhZStBZ5q/

It was a labor of love, but I finally finished creating eight new progression videos. Once they're out, I'll get them uploaded to my site. Thanks for the nudge to get these done. gfletchy.com/progression-vi…
