Problems and Solutions
CMS Inclusion Initiative
Thanks to the financial support of the Actuarial Foundation of Canada and the RBC Future Launch program, the Canadian Mathematical Society was able to offer free registration to Black and Indigenous students as well as to a number of female-identifying students.
The CMS is committed to equity, diversity, and inclusion in mathematics and encourages teachers to inform their students of this initiative.
Wow!
…and this includes one student in grade 4 and three students in grade 5!
