The Pacific Institute for the Mathematical Sciences, the Centre de recherches mathématiques, The Fields Institute and the Atlantic Association for Research in the Mathematical Sciences are joining forces to develop a series of educational modules with the intent of inspiring pre-service and in-service elementary school teachers to further develop their mathematical thinking. The goal is to support their future and current practice with activities, and the development and connection of ideas that will help them tackle the ever-changing provincial curricula. We want to tease out the mathematician in them. An inspiring teacher is the most valuable school asset. We remember those teachers who motivated and “fired us up”, for they played a vital role in shaping who we are today. Our plan is to bring together a group of mathematicians, math educators, teachers and people with Indigenous knowledge together to develop methodologies to inspire teachers to strive for and expect success for students from diverse backgrounds.
