Thinking Changes Everything.

Research and practice focused on Building Thinking Classrooms®, mathematics and numeracy, teacher learning, and the conditions that support meaningful instructional change.

Explore Learning Opportunities

Learning and collaboration can take many forms—from facilitated sessions and classroom-based work to coaching, collaborative inquiry, longer-term partnerships, and research.

Meet Judy

I’m Judy Larsen, a mathematics educator, researcher, teacher educator, and professional-learning facilitator. My work moves between university teaching, research, classrooms, and professional learning spaces, with a particular interest in how thinking, participation, identity, and relationships shape mathematics learning.

Alongside my academic work, I collaborate with schools, districts, and educator communities through workshops, coaching, co-teaching, classroom-based inquiry, and longer-term professional learning.

Experience First

Learning by doing, not being told.
In all of my work, I prioritize experience first. Participants begin by experiencing practices and strategies as learners before unpacking them as teachers. This also goes for lesson design for learners themselves, where experiencing the concept is at the heart of accessing deeper understanding.

A space to try, stumble, and grow.
Real change asks people to take risks in front of others. At the heart of this, every session I lead prioritizes creating spaces that feel safe enough for that—inclusive, low-stakes, and genuinely welcoming. Participants leave with the confidence to use what they've learned, not just a list of new strategies.

Bridging Research & Practice in Mathematics Education

Work draws on research in teacher learning, mathematical identity, numeracy, and classroom participation, while staying grounded in the realities of teaching. Complex ideas are made accessible, practical, and useful without oversimplifying them.

Longstanding Building Thinking Classrooms® Experience

Experience with the Building Thinking Classrooms® framework spans its early development through research, university teaching, workshops, coaching, co-teaching, classroom observation, and sustained district partnerships.

Responsive & Sustainable Professional Learning

Rather than delivering a fixed program, professional learning is shaped around the educators, goals, and systems involved, with opportunities for workshops, collaborative inquiry, coaching, classroom-based work, and follow-up over time.

From Educators & Collaborators

“The workshop was interactive and engaging the entire time. We explored ways to have students work on math without feeling like they were working on math. Participation was high and people left feeling a sense of accomplishment.”

— Richmond, BC PD Participant, August 2025

“Judy Larsen’s openness, calm approach, and support really helped make the Building Thinking Classrooms work in our school feel accessible and meaningful. The way she engaged in classrooms and debriefed with teachers has already sparked some great conversations.”

— Manitoba School District Coach, November 2025

“Judy is a fantastic facilitator who created active, hands-on learning experiences that I’m excited to apply in my math classroom! ”
