@AlexOverwijk Congratulations!

[Ali Walker @AliWalker24]

Extraordinary night in downtown Boston.

Brazil, Morocco and Haiti fans + the Tartan Army moshing to NO SCOTLAND NO PARTY.

Only the World Cup.

In 1996, the median house in Massachusetts sold for about $150,000. If prices since then grew at the rate of inflation, you could buy a standard home today for ~$308,000.

But they didn't. The actual median price in 2025: $638,000. #mapoli

My school moved into a new building a few years ago, and I went from a tiny behind-the-library office to one with a gorgeous, full-wall window, and... I love that window.

[Nicholas Fabiano, MD @NTFabiano]

Sitting by a window is associated with significantly improved cognitive performance.

New #SlowRevealGraph Blog
Facilitation Tip: First Slide Print Out

While the slow reveal graph routine is discourse driven and focuses on a shared visual, giving students a print out of the first slide can support access into the conversation. https://t.co/OPXWBPBc4g

It's @theericklee at #OAME2026 coming from the east coast to talk about the power of the first 5 min of class. With references to lots of #math class favs & including other curated math resources, check them all out here:

Great session from @webbkyle & @KirstDy on how to remix an already rich problem at the @OAMElearns #OAME2026 conference. They also shared some great problem solving resources:

Students who used AI to study remembered less than those who did not.

New newsletter: MODERN FATHERHOOD WOULD BE UNRECOGNIZABLE TO A 1950'S DAD

Compared to their Boomer parents, childcare time among Millennial dads has more than doubled.

Compared to their Silent Generation grandparents, it’s nearly quadrupled.

You will be hard-pressed to find any part of day-to-day modern life that has changed more in the last half-century than the way today’s parents—and fathers, in particular—spend their time.

The new American dad is more present and more exhausted—but also, more satisfied with life. What's behind this half-century transformation? Today's piece combines history, economic analysis, and gorgeous charts galore from @AzizSunderji

[Hunter📈🌈📊 @StatisticUrban]

It took over 100 years, and many predicted it was impossible, but today Sabastian Sawe broke the two-hour barrier for running a marathon.

Since 2002, all of the record-holders have been from high-altitude regions of Kenya/Ethiopia.

[Jenna Laib @jennalaib]

@m_pettyjohn To be honest: only a few.
I do it all the time on my own, but it’s not scaling up the way I’d like. Still: I haven’t given up hope!

And I’m always happy to carry the MTBoS torch! 🔥 Great to see your name back in my mentions!

"But It Looked So Good: Checking On Student Thinking"

They have lots of names: exit tickets, cool downs, etc. Here's why I think that quick, low-stakes formative assessment is so important. (told through grade 3 fraction work)

I would be SO much better at math if my teachers bothered to see if I was getting it in the moment. Now, as a teacher, I never let them walk away confused

[John Bistline @JEBistline]

With the Boston Marathon today, a good time to re-up one of the greatest figures in sports data: the distribution of marathon finish times (n=9,789,093). The spike at 4:00 is not a coincidence.

[Jenna Laib @jennalaib]

@besttrousers That was my first thought when I saw this. 😜

Self-reported height vs. actual height

As I often say: There are charitably seven, plausibly four, but really just one city in America

You should read the retweeted piece from math pedagogy expert @jennalaib
Me?
I’m slightly bothered that 5 appears to be used more frequently than 4, but less frequently than 1-2-3.

[Jenna Laib @jennalaib]

@realJ_Mitchell Are those numbers programmed settings? I got so into the math of the commercial-grade microwave in our staff room! But ultimately the microwave was re-homed because people did not like how much thinking went into the process.
