Monthly Math Challenge
Each month, we are offering sets of engaging math challenges tailored for both primary and junior students. Designed to ignite classroom discussions and foster deep mathematical thinking, these...
Math isn’t tedious—it’s mind-blowing. Here are 59 talks that prove it. abakcus.com/59-mind-blowin…
All you need is a deck of cards for this game! Students work to get rid of all their cards by devising math statements that equal 7. Start w/ addition/subtraction for primaries; challenge juniors to include multiplication/division. Free lesson: oise.utoronto.ca/robertson/less…
My class is truly great chat in the morning!
Here's a way to get kids noticing and wondering about angle measures!
On October 18, step back into the halls that shaped your journey at the @jicslabschool's Alumni Homecoming! Tour Canada's #1 lab school, connect with your classmates, and hear from special guests. RSVP for this spectacular afternoon event, here: buff.ly/bknlJ4L
The California Department of Education published a great resource about what is frequently thought of as math modeling but is NOT. Read more here: robertkaplinsky.com/what-isnt-math…
What if our students experienced mathematics as beautiful, playful, & full of wonder? Join our webinar that will invite teachers to rediscover the joy in numbers as we explore elegant patterns, creative problem solving, & the fun of mathematical thinking: nctm.link/8k8FA
Hula hoops + classroom objects are all you need to introduce young children to the principals of Venn diagrams. Students decide the sorting attributes and work together to fill their 3D diagram. How do they explain their sorting decisions? Free lesson: oise.utoronto.ca/robertson/less…

An insightful interview with long-time Robertson Program partner, Dr. Zack Hawes, on the power of spatial reasoning in shaping math and science learning.
“Spatial thinking is a fundamental, yet often neglected, aspect of human cognition.” Zachary Hawes tells @aishaschnell how central spatial thinking is to STEM learning. #EdChat boldscience.org/the-psychologi…
Learn about the importance of symmetry in play and development, in spatial reasoning, and resources that can be implemented within the classroom to improve understanding. oise.utoronto.ca/robertson/blog…
Once students can multiply numbers between 1 and 6, challenge them to expand their skills with “Evens & Odds.” This 2-person game extends into multiplying larger numbers, exploring probability, and recognizing prime and squared numbers. Free lesson: oise.utoronto.ca/robertson/less…
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…
There’s an incredible range of activities you can get from a 2x4 grid outside. Maths, coding, dance, music, PE - or even just a little game for a smile! #playinupperprimary
We love the math possibilities found in a deck of cards! 99 is an adding/subtracting game challenging students to determine a strategy to keep their total score under – you guessed it! – 99! * All you need: A deck of cards oise.utoronto.ca/robertson/less…

99
In this collaborative game, students try to keep the cumulative total under 99 until the deck runs out.

Happy math storytelling day! In an earlier blog, Dr. Julie Comay writes about the benefits of integrating stories into math class + what to consider when selecting stories to support math learning. #MathStories #ElementaryMath oise.utoronto.ca/robertson/blog…
Common numerators is an underrated strategy for comparing fractions
