Learning basic math facts using playful memorization | The Robertson Program | Ontario Institute for Studies in Education When the Ontario government rolled out its new math curriculum in 2020, it was touted as a “back-to-basics” approach.

Math fluency isn’t just memorization or strategy—it’s both. This article explains how mental math, automaticity, and playful learning can work together to support all learners. #MathFluency #MentalMath #NumberSense #MathStrategies www.oise.utoronto.ca/robertson/bl...

Dice War Players aim to collect all the dice in the game. They roll to get a score, and the highest roll wins all the dice.

Welcome back! Teachers can start off the year with this small group activity where students will roll high to take it all 🎲 One throw decides who walks away with every die. #DiceGame #WinnerTakesAll #Probability www.oise.utoronto.ca/robertson/le...

From all of us at the Robertson Program, we hope you have a restful winter break! We can’t wait to share more exciting content with you in 2026!

Missing Puzzle Pieces Students develop reasoning and discussion skills by identifying the missing piece of a puzzle.

Students identify the missing piece of a puzzle using key characteristics, including number of sides, length of sides, angles, and lines of symmetry.

Unifix Counting Towers Students get their minds and hands engaged with numeracy while making Unifix Towers.

Students are invited to select a number card, read the number and build the corresponding "tower," to get their minds and hands engaged with numeracy in this one-on-one activity with an educator. www.oise.utoronto.ca/robertson/le...

Whole Number Bias and 3 Misconceptions about fractions in Junior Math | The Robertson Program | Ontario Institute for Studies in Education Whole number bias is the tendency to apply or misapply one’s understanding of whole numbers or natural numbers – the numbers we typically count with – to rational numbers. It makes sense that people m...

Junior students often have misconceptions about fractions such as incorrectly saying that one quarter (1/4) is larger than one third (1/3). Read to learn about effective fraction teaching strategies and activities that can be incorporated in the classroom. www.oise.utoronto.ca/robertson/bl...
