New paper led by Ilyse Resnick! Informal fraction knowledge grew Gr1–2 w/little instruction; nonsymbolic>symbolic; “half” led in Gr1, 3rds/4ths in Gr2; early fractions predicted later math beyond number sense (Resnick, Viegut, Barbieri, @noranewcombe.bsky.social & Jordan) tinyurl.com/Resnicketal2...

There has never been a Canadian Prime Minster that has used this kind of language since 1945. It's astonishing. The most powerful statement since Freeland's speech on Canadian foreign policy in the House in 2017 (which was also a response to Trump) - and this goes well beyond that.

Just so my American friends and followers get an idea of what the official mood of Canada - L'ambience officielle du Canada - is at the present moment.

"If great powers abandon even the pretense of rules & values for the unhindered pursuit of their power & interest, the gains from transactionalism will become harder to replicate" -- Carney's speech at Davos is an extended criticism of the damage Trump is doing (though he's not mentioning his name)

If you are a Canadian, and you travel to or support the United States in any way, you are a traitor.

The Prime Minister of Belgium speaks:

This is the way.

While the eye of Sauron may have recently averted its gaze, a good reminder it is always only one post away. There can be no more normal. No more “but my kids like Disney” vacations. No more “but it’s such a good conference”. No more appeasement.

As expected: Russian Foreign Minister Sergei Lavrov: “Trump said that Greenland is important for the security of the US. “Crimea is equally important for the security of Russia.”

Even on here, I’ve noticed a distinct shift from people outside the country that’s essentially, “This isn’t funny anymore, fix your shit America.” I just wonder if our congressional invertebrates are feeling that at all.

It seems pretty clear that if Carney is trying to reposition Canada in the global auto market, and especially to be a player in EVs as the US drags its feet, he’s going to need to think about recognizing or aligning with EU/JP auto safety standards.

Canada cannot stand by while Donald Trump uses tariffs and intimidation to pressure allies who are doing the right thing. Trump’s threats toward Greenland should terrify people and send a chill through every democracy. (1/4)

If the draft dodger says he was thinking "purely of peace" before not receiving the Nobel Prize, then it would be interesting to hear his definition of peace, given the number of countries he has bombed during that time.

It is not Europe's job to protect us from the consequences of our elections. They've got a responsibility to defend Greenland from imperialist aggression.

This is what happened in our neighborhood yesterday. ICE snatched a human being off of our streets, roughed them up badly, and then pepper sprayed legal observers as they documented it all. This is a daily occurrence happening all throughout Minnesota right now.

It's bizarre that some politicians are trying to behave as if the US president were sane, or capable of reason or moral judgement.

“If he invaded us, we would wait him out like bad weather. “We know how to wait. We hunker down for storms. We could wait 10 or 20 years.” 2/2

Danish officials will not attend Davos as tensions with the US escalate, Bloomberg reports.

America, this guy is making you look like idiots

32% of Americans believe that Trump's policies will increase peace & stability in the world....

Trump introduces a tariff for goods from The Netherlands. Great. Bring it on. I am happy to suffer any damage to our economy, and subsequent reduction to my wealth, for doing the right thing (being willing to protect Greenland).

The vast majority of Americans across the political spectrum don't really think of non-Americans as real people. For them events outside the US exist purely as a backdrop for disputes within it.

Christ. I remember years ago standing in the Minnesota History Center at an exhibit about Hmong refugees thinking this is what America is all about. Alas.

Words to love by, fellow Canadians. Let me leave you with this thought: the US Midwest usually has about 9 days of oil in storage. Canada supplies 100% of Midwest oil imports. 9 days. Think about it.

Canada must not do this. It is a mockery of international political governance, legitimizing the idea that Trump can simply push aside other countries' sovereignty. www.politico.com/news/2026/01...

As a Canadian, my advice: do it anyways.

Canada needs to get in on this in a robust way, and show support for Greenland, Denmark, and other northern European allies, for two important reasons: 1) It's the right thing to do. 2) We could very well be next.

Territorial integrity and sovereignty are fundamental principles of international law. They are essential for Europe and for the international community as a whole.

🤷

Europe has - in technical terms - an absolute sod load of potential economic leverage over the United States. It has turned the other cheek due to security concerns. The US seems intent on demonstrating that it will not guarantee European security. So Europe may start using that leverage.

Trump launches a trade war with former European allies over Greenland.

Carney on the 'new world order.'

The President of the United States just extorted a second-hand Nobel Peace Prize from the leader of the opposition of an authoritarian regime now backed by the United States.

Q: “Is China really the right kind of partner for Canadian industry?" Joly: "Listen, we've been clear-eyed. We are eyes wide open."

Prime Minister Carney states that the progress made on Canada's partnership with China "sets us up well for the new world order."

The world is on fire, but at least I got my grade in on time.

Walz: "What's happening in MN defies belief. News reports simply don't do justice to the level of chaos & disruption & trauma the federal govt is raining down... This long ago stopped being a matter of immigration enforcement. Instead, it's a campaign of organized brutality against the people of MN"

There is no coming back from all of this. No election can fix this. US soft power is toast, reputational damage is going to take years to recover, if ever. And that is if we all survive this US-led horror show.
