“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 my pursuit of continued math professional development. I completed my Master’s through SFU with a thesis titled: Learning from Learners.

My great passion is being available for learning alongside adults and students through my role as Curriculum Support Teacher K-7 in the beautiful Comox Valley. I aspire to help children, adults and families to find healthy perceptions of themselves as mathematicians. I view math lessons as great ‘learning time’.

Lifelong learning is one of Darien’s core beliefs, and is something she tries to encourage in her students, and her young daughter. She strives to help her students develop an appreciation for the wonder of mathematics and actively searches for opportunities to provide her students with ways to experience it. Frequently on the go, she really appreciates quality time with her daughter, and the rare quiet moment to relax with a good book.
