About
I'm Peter Mant. I've been teaching math for twelve years — first in London, then in New Jersey since 2020, where I currently teach middle school in Jersey City.
I discovered Peter Liljedahl's Building Thinking Classrooms framework and it transformed the way I teach. The name comes from a core BTC practice — passing the marker on the vertical surface so every student is actively doing the thinking, not just one. This toolkit grew out of a desire to make BTC genuinely easy to run day-to-day: randomising groups, picking students, timing tasks, and generating thinking questions.
