Zero is a powerful number with a complex history and surprising significance in mathematics. Learn about how the brain interprets zero and the history of the number, along with ideas on how to start conversations about zero in the classroom.

This three-part, hands-on lesson uses baking to teach students how to understand, compare, and work with fractions. Students measure ingredients, double and triple recipes to practice adding and multiplying fractions, and identify and compare fractions in their own recipes.

Number lines make explicit and build upon pre-existing spatial-numeric intuitions, support children’s growing understanding of ratio, proportion and scaling, and help students to construct and internalize a “mental number line” that continues to develop in complexity from kindergarten through university mathematics and beyond.

A three-part lesson exploring how sound works and how we perceive it. Through classroom experiments—such as testing how sound travels through different materials and environments—and neighbourhood sound walks, students will fine-tune their listening skills and develop an appreciation for the subtleties in their surroundings.

In collaboration with YAAACE, The Robertson Program set out to develop a series of engaging activities aimed at fostering a deeper understanding of probability and statistics among a fifth-grade competitive basketball team.

Quilts are holders of stories about community, culture, tradition, celebration – and even math! Picture books focused on quilts can help students build skills, such as spatial sense skills by thinking about patterns, shapes, angles, symmetry and much more.
