Resources for teachers

In considering this year’s International Day of Mathematics theme, “Math for a Better World”, we are inspired to share with you the work of Canadian painter Jock Macdonald (1897-1960), who was inspired by mathematics himself, and incorporated this into his visual imaginings of the world around him. He was always on the lookout for patterns: in nature, in the universe, and in his stunning abstract works. For Macdonald, this interest in geometry and patterns was a way of connecting on a personal level with the natural world. 

The Art Canada Institute’s Teacher Resource Guide invites students to use Macdonald’s abstract visual language in order to practice using equations to calculate the area and circumference of circles.


The following resources may be useful for teachers and other educators:

Canadian Supported by the CMS

CMS Mathematical Competitions

Come participate in the Canadian Open Mathematics Challenge (COMC), held each November.  Students from across Canada and around the world are invited to compete in this written competition held at their own schools.  Besides prizes and awards, the top students are get invitations to the elite national math competitions such as the Canadian Math Olympiad and from there, they could be invited to train and represent Canada at international events such as the APMO, EGMO and even the International Mathematical Olympiad!


CEMC Courseware

Features lessons, interactive activities, enrichment challenges, and practice with feedback, provided by the Centre for Education in Mathematics and Computing (CEMC) at the University of Waterloo.
