I love the way he not only proves he is alive, he also subtly taunts Ron DeSantis by stealing his uber-masculine white boots look. He is back and he is warmed over!

I hold Republican members of congress responsible as well. They could decide that American lives matter than their utter obeisance to Dear Leader, but they not only lack the courage, they also lack the moral compass.

It takes some very special skills to be able to bankrupt 4 different casinos. Trump is scaling up now, to be able to bring financial ruin to the entire country.

I wonder if Trump, with all his knowledge about grass, can tell us why this particular patch of grass and weeds is looking so raggedy.

At the time when having a fourth estate became crucial, our press has become absorbed in figuring out the very least they can do and still look like they are reporting.

I'll be asking Kevin Kiley for an in-person town hall. A virtual town hall won't do the trick, as he will screen the questions and avoid the ones he doesn't want to answer, like the one about why he would vote to protect the identity of the pedophiles on the Epstein tapes.

Watch carefully how the network news selects which video of the ICE protests to present, to understand what conclusions they intend for their audiences to make. We all need to realize what our country is up against, as MSM outlets are trying on their own versions of being state news.

Republican Rep. Mike Flood appeared before his constituents in Nebraska for a town hall that turned ugly as he tried to defend Trump’s “big, beautiful bill." Unfortunately, Flood hadn’t actually read the bill...

Trump wants to give almost $5 trillion in tax handouts to billionaires and billionaire corporations — paid for on the backs of seniors, veterans, public workers, and little kids. We can’t let that happen.

Elon Musk just shared a post that said public sector workers, not Nazi dictator Adolf Hitler, murdered millions of people, marking the billionaire’s latest Nazi-related post as he and his electric vehicle company face continued backlash and boycotts. Ghastly, right? www.forbes.com/sites/antoni...

Also, IMO that process is the secret sauce for teacher growth. Paying more attention to individual student thinking is a part of the most wondrous feedback loop.

If a teacher pays enough attention to each student to appreciate their real strengths (not just in skills, but strengths in how they think and the situations in which they think best), then their students, especially those most apt to be tripped up along the way, are more likely to learn and thrive.

The thing I can't help but notice about the choices that DOGE is implementing is that they all reek of Social Darwinism. Musk apparently believes that there's money to be made in trodding on the downtrodden, in expanding each and every existing gap in outcomes for Americans.

Agreed, fractions are a way of writing a rational number. Otherwise, we might have to call 0.131313… a fraction, as it is a way of writing 13/99.

I really like that you use number lines in this. It should help to ground the reasoning about the units in the solution.

Conclude that √2 is approximated by 7/5. Iterate. The next approximation you find is 17/12. Continue this and you’ll find a sequence that converges √2. This well-known sequence is what you can also find using Newton’s method, so it converges quadratically (interestingly fast). 2/2

Start with a fraction close to √2, say 3/2. Thus a square of side 3 has area close to two squares of side 2. Line those up along a diagonal of a larger square. Fill in the lengths and argue that the area of the large square (side 7) must be close to the area of the two squares with sides 5. 1/2

Squares of area 2^2, 3^2, and 2^2 are lined up along a diagonal of a square of area 7^2. This creates two overlapping squares of area 5^2, also inside the square of area 7^2.

My hunch is that subitizing can provide an early success for a student who could really use a first success. Also, subitizing supports the number sense behind ten frames, and the visualization of friends of 5, friends of 10, etc. More so if you use a rekenrek.

I'd be hoping to see some students drawing pictures -- perhaps if I made multilink cubes available -- leading to a nice hands-on proof.

The first thing I ever did with a computer was on a Wang 3300, in 1971. It was wild -- you entered your program into the computer by punching holes in a long paper tape that you fed into the computer.

But it does present a real structural challenge, one that requires much much more than the right view of it. I'll be more relaxed about this when we know some models of low SES high schools who see an increase in their production of graduates who find STEM careers.

I think that the ways you tell students that you like them and the subject are not about planned, overt actions you take. It is more like the state of mind you have as you teach. I believe that primary teachers generally have a heightened awareness of this aspect of teaching.

In The Tipping Point, Gladwell spoke about how someone could watch just a few seconds of video of someone teaching and their evaluation of the teacher would match the end of semester evaluations. If the answers to the first two Qs are Yes, this probably happens on the sly, consistently throughout.

When I look at mathematical examples that surprise me and I want to make sense of them, I’ve learned to ask myself, “What’s the coolest possible thing that could be going on here?” The eventual explanation is always at least as cool as the one I imagine. So my sense is that I am discovering math.
