Past President

Michael Pruner is a high school mathematics teacher from North Vancouver, BC and the past president of the BC Association of Mathematics Teachers. Michael recently completed his masters degree from SFU in mathematics education and is now working on his PhD in the same department. Michael is an advocate for teaching in the Thinking Classroom model, and believes that mathematics is a social endeavour best learned through collaborative activity in rich tasks. Through the BCAMT, Michael has had the privilege of visiting classrooms all across BC sharing his experience and knowledge of developing and maintaining Thinking Classrooms.

Outside of teaching mathematics, Michael likes to spend time outdoors with his family cycling, skiing, and camping.


Colin McLellan moved to Vancouver from Alberta in 2004, graduated from the UBC Teacher Education Program in 2006, and has been teaching at McNair Secondary in Richmond ever since. He is constantly reflecting on and changing his practices in the pursuit of something just a little bit better. Although this makes a lot of work for him, he strongly believes that the day he stops changing things is the day he needs to stop teaching. He joined the BCAMT executive in 2008 and has been secretary since 2011. He and his wife, who is also a math teacher, have two young kids who love to count stuff!


Jen Carter is a Numeracy Coordinator for Vernon School District and an instructor for UBC Okanagan. As a prior elementary teacher and administrator, Jen had a deep curiosity about the discomfort students and teachers felt around mathematics.  This personal inquiry led to her current “passion” and role working alongside teachers to explore and rethink what mathematics education currently is, and the possibilities of what it can be for students.

Outside of her work in schools, Jen can be found taking classes at a local pottery studio, enjoying the outdoors in the beautiful Okanagan, or paddleboarding at her cottage on Shuswap Lake.

Marc’s greatest source of professional development comes through engaging in the blogs and tweets of the #MTBOS (Math Twitter Blog-o-Sphere). Marc’s hobbies include some TV and movies, and any activity that will take him into the beautiful nature of BC. Oh, and beer, Marc likes beer–the darker the better. Marc has four daughters, who in addition to being a lot smarter than he was at their age, are also inspiring through their music and dance. Although, Marc has been known to break into Irish dancing during social events.

Elementary Representatives

Adam Fox is a kindergarten teacher in North Vancouver. He recently completed a Master of Education Curriculum & Instruction: Numeracy at SFU, and tends to say “maths” not “math.” He has a degree in computer science and in a previous life he was an IT consultant. When he is not “herding cats” he can be found attempting to play football (soccer, eh!) or ski on the local mountains.

Debbie Nelson: “Math was too much answer-time and not enough learning-time.” A six-year-old’s response to why he didn’t like math was enough to spur Debbie Nelson’s pursuit of continued mathematics professional development. She completed her Master’s through SFU with a thesis titled: Learning from Learners.

Debbie’s great passion is being available for learning alongside adults and students through her role as Curriculum Support Teacher K-7 in the beautiful Comox Valley. She aspires to help children, adults and families find healthy perceptions of themselves as mathematicians, and views mathematics lessons as a great “learning time.”

Alex Sabell has been an elementary school teacher in the Surrey School District since 2010 during which time she earned a Masters of Education in Curriculum and Instruction, with a focus on numeracy. This fostered Alex’s passion for mathematics which is now an integral part of her teaching practice. She strives to provide learning opportunities for students that change the way they see and experience math. Alex believes in creating a caring, collaborative learning environment for her students that promotes the building of concepts through exploration and discovery. Her teaching methods have the goal of creating curious, confident and enthusiastic learners. In 2018, Alex received the Outstanding Elementary Teacher Award, as well as the Ivan.
