[New Post] Ontario Math Links - My favourite #math related links from this week: ontariomath.blogspot.com/2026/02/math-l… Links and help from @OAMEtalks @howie_hua @edutopia @artWorld and more #MathChat #MTBoS #iTeachMath

🧩 WORKED EXAMPLES! In this week’s edition of ⚗️DistillED, I unpack what worked examples are, why they reduce cognitive load, and how they help students move from watching expert thinking to applying it independently in the classroom. Have a read: newsletter.jamieleeclark.com/p/worked-examp…

Dylan Wiliam calls Cognitive Load Theory “the single most important thing for teachers to know.” This guide summarises core CLT ideas and highlights six high-impact strategies for reducing overload. It focuses on the classroom levers teachers can pull right away. CLT goes much deeper, of course — transient information included — but these strategies offer some of the fastest gains. 💪 Free HQ copy if you want it: jamieleeclark.com/graphics

@StudyMaths Do you have the first slide but blank available?

You're probably familiar with students counting out loud as a class, but imagine what happens when the conversations when students start counting at 1 1/2 and increase by 2 1/4 each time. Read more about what happens from Sadie Estrella: iamamathnerd.wordpress.com/2014/01/04/cou…

What number comes next? How do you know? The decimals square is great for visualising tenths, hundredths, thousandths (and further!) mathsbot.com/tools/decimalS…

How would you explain division? There are two ways we can think about division and understanding these models can help with fraction division.

Printable bar models. Super simple to use, great for building fluency. I'll often set the whole to 180 (like in the screenshot) before starting work on angles. mathsbot.com/printables/bars

Targeted math fact warm up idea…

@cjansseune @tvdsbmathk8 @KnollwoodPark1 You should post one of these on the J/I “On Track with Math” bulletin board 😊

Thank you, @tvdsbmathk8, for the First 10 Days of Math! Love the use of different manipulatives. @KnollwoodPark1

A good mental math strategy to have: doubling and halving

Completion tables are a great way to get pupils working backwards and add an extra layer of challenge. Here's one for the Four Operations. mathsbot.com/tables/fourOps

Making it real! Applicable - they can SEE the connection to themselves… amazing!

For seven seasons and 122 episodes, Canadian children were transported through television to the world of a department store where amazing things happened. The show remains a high-water mark of children's entertainment in Canada. This is the story of Today's Special! 🧵 1/9

@robertsonprog We love Cuisenaire rods and focus on the spatial first. So many great tasks and games to learn about the space numbers take up. Through play we can experience place value, which is why I believe the students are so flexible with their thinking.

Welcome back! Many teachers start the year with number sense - but what if that’s fuelling math anxiety? Discover how playful spatial reasoning activities spark joy, reduce anxiety, and build confidence in math. oise.utoronto.ca/robertson/blog…

I am still surprised to find teachers who haven’t heard of this series. It is an absolute MUST watch full of great practice with really practical strategies for implementation.
