Mark Hansen has been involved in education for nearly 2 decades as a classroom teacher, Master Teacher of Mathematics and Deputy Principal. He is also the father of 4 children. He has a passion for learning and for igniting that passion in others, particularly in mathematics, where his work has been featured in educational journals. His goal is for schools and societies to have students who are confident, creative communicators in mathematics, that they see the purpose in it and enjoy engaging with it.
