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. humanrights.ca/story/canadas…

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.
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. Learn more: bit.ly/4jp99Bq

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.

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.

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.” theconversation.com/chinese-…

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 🙏🏽
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.

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!

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 🍰

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.

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.
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? educationendowmentfoundation…

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.

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.
“In fact, there is surprisingly little hard evidence that any of these approaches, on their own, are effective in shrinking academic disparities. To do that, teachers should consider augmenting their equity initiatives with explicit instruction, regular feedback, and lots of retrieval practice, all of which have been shown to help struggling learners.” Bingo! This is the core issue. It’s the opportunity cost of investing time, resources, and money on what has yet been proven to work and not what has been proven: explicit instruction, retrieval practice, and formative assessment with feedback. Teachers, schools, and districts only have so much bandwidth and frequently it is not spent on what decades of research show work to help all students learn.
