Let the games begin!!! Math games are being used as a way to support repetition of a new skill or strategy, allowing time for teachers to work with a group for small group instruction.

1996.

It's not ancient history - that's the year the last residential school closed in Canada.

September 30 is National Day for Truth and Reconciliation - we hope you'll take a moment to read about the history and legacy of residential schools. https://t.co/rOZ3weknOw

I wasn’t surprised @tdsb improved achievement, but I was floored by just how much.

I’m proud of our Grade 3 results, a culmination of 3 years of building additive reasoning in K-3 students.

Kudos to @TDSBmath & senior leadership for keeping the focus on things that matter most.

[Toronto District School Board @tdsb]

This year’s @EQAO results show significant progress across the TDSB, with Grade 3 and 6 literacy and math seeing some of the largest increases in decades.

Happy Day 1, teachers!

There are lots of changes and challenges this year, but think of every challenge as a new opportunity. At least that’s my mindset going into it all.

Enjoy meeting students today and have a hope you have a great start to the year.

My statement on Canada-U.S. trade negotiations:

[Jason To | 杜澤信 @Jason_To]

@dperkinsed Math is “relentlessly hierarchical,” as Anna puts it. That means a new math idea can be built from prior ideas, which many students have to some degree. Students are experts in the things they know, so that can be used in an inquiry setting to teach new ideas.

[Jason To | 杜澤信 @Jason_To]

@dperkinsed Thank you for continually trying to break down the tribalism. I agree, it’s exhausting.

[Drew Perkins @dperkinsed]

Saying inquiry teaching doesn't work because you struggle with it is kinda like saying meditation doesn't work because you couldn't quiet your mind.

Often, the educators who dismiss inquiry-based learning seem to lack the exact skills and mindset it's designed to build.

@nsachdeva2019 @ToddTruitt76508 Is destreaming perfect right now? Of course not. But it's had 5 years vs. 100 years of streaming in Ontario.

This study's recommendation of providing stretch opportunities for higher-attaining pupils is a good one, and I'll make sure to support that in my role.

[Jason To | 杜澤信 @Jason_To]

Let's dig deeper...

The EEF gave the study 2 out of 5 for evidence strength due to attrition, small sample, not controlling for teacher quality, etc.

The conclusions warn mixed- and ability-grouped classes about issues already known and do not call to end mixed classes.

[Anna Stokke @rastokke]

New EEF study finds lower-attaining students are NOT harmed by ability grouping, but higher-attaining students are held back in mixed classes.
Advanced students don't get enough attention in my view. What is the goal of public education? Getting all students to a minimum competency level has to be one goal. But is there not an obligation to provide an environment for students who have surpassed minimum competency to keep moving ahead?

[Jason To | 杜澤信 @Jason_To]

@nsachdeva2019 @ToddTruitt76508 It's a well-designed study & its results are worth considering, but it's England-only & notes the few mixed attainment schools & high attrition.

Jumping to conclusions is NOT being evidence-informed. What are the study's recommendations? OECD recommends against tracking...

[Jason To | 杜澤信 @Jason_To]

Ontario elementary teachers can exercise judgement, but need more time to collaborate and also strengthen the consolidation portion of math learning.

“Chinese and Canadian approaches to math teaching have a lot to learn from each other.”

It was a great 3-year title run, but every streak must end. Congrats to Greg (AngryJay) for making NHL94 history & cementing 🐐 status.

I’ll be back to try and start a new streak. Thanks to Darrell at @nhl94dotcom for giving so much time & energy to running this every year 🙏🏽

[nhl94.com @nhl94dotcom]

Congrats to Angryjay93, who did something that has never been done in the history of the NHL94 world championship. Winning on both consoles.

A dominating performance on Sega Genesis 16 wins, 0 loss

Won the SNES final, 3 games to 2 against the reigning champion, The Professor.

[Maya Goldwasser @mrsgoldwasser]

Well that was fun! My mind & ❤️are full. I missed my Mathies! Thanks @OAMElearns for another great #oame2026 conference. Thx to those who joined my session. Can’t wait to bring all the new learning back to @FaywoodABC. See you all next year!

[Jason To | 杜澤信 @Jason_To]

This year's @OAMElearns conference was amazing! It’s always so great to connect with & learn from math teachers, consultants, and coordinators from across Ontario. I now know more about the kindergarten play continuum!

Getting to chat with @pwharris was icing on the cake 🍰

[Jason To | 杜澤信 @Jason_To]

Ability-grouping advocates can’t solve the issue that plagues every jurisdiction that does it: the gross overrepresentation of marginalized groups by race, SES & disability into lower streams taught by less-qualified teachers that lead to fewer opportunities and worse outcomes.

[Jason To | 杜澤信 @Jason_To]

It was a pleasure earlier this week meeting with other members of the @LDatSchool Advisory Committee. Great brainstorming about system change, resource development, pedagogy, and coalition building to support students with LD & ADHD.

Students who take notes by hand get better grades than those who use laptops, especially in STEM fields.

[Drew Perkins @dperkinsed]

If learning occurs at the point of challenge then struggle, with guidance, is essential.

[Dana Palubiak @DanaPalubiak]

If education research is “weak and sloppy,”

then we should be cautious about all claims of certainty.

Not just the ones we don’t like.

You can’t dismiss CRP, SEL, and UDL as “unproven”

while treating explicit instruction and retrieval as settled science.
