Hot take: We need to stop racing to the final answer in math class.

If we only teach the procedure to get the answer, we would get so many false positives. Yeah, they got the right answer, but do they actually understand the math?

Rosenthal prize winners for 2025

Had a wonderful evening at MoMath for the 2025 Rosenthal Prize presentation. It was great to meet everyone and to chat about the intersection of math, magic and music. @momath.bsky.social

I had the opportunity of a lifetime to work in Barcelona, Spain where I taught 6th graders and presented to educators in Spanish about Open Middle. It was even covered in a newspaper! I am so grateful for this amazing opportunity.

Ep 27 - Jason To - Think Thank Thunk Jason To joins Kyle to bridge the gap between cognitive science and Thinking Classrooms. Learn how cognitive load and collective memory may help explain why Building Thinking Classrooms works.

Check out the latest episode of the @thinkthankthunk.ca podcast to hear me rant about inquiry-based vs. explicit instruction and how they fit:

or wherever you get your pods.

There are four book covers with the largest reading, "Building Thinking Classrooms in Mathematics, Grades K-12." The other three are translations of the cover in French, Spanish and German. Text around the book covers reads, "Celebrating 5 Years since publication" and "Translated into 15 languages." In the bottom left corner, the text reads, "Let's keep building thinking classrooms together!"

Celebrating 5 yrs since Building Thinking Classrooms in Mathematics, Grades K-12 was published!

🌍 The book has sparked a movement, been translated into 15 languages & inspired classrooms everywhere.

Here’s to curious minds, thinking deeply and bravely!

This lesson uses a time lapse thermometer video as a context for discussing integer operations and absolute value. The video should provide some added meaning to the classic temperature drop problem.

After watching our book ship worldwide, my own copies finally landed. Surreal to say the least!

So excited about what @pgliljedahl.bsky.social and I created, and even moreso to get this into the hands of teachers!
