Our Mission

Multiplicity lab was founded at Northwestern University’s School of Education and Social Policy to support the teaching of mathematics as an ambitious, expansive, and just pursuit. We connect research in the learning sciences and mathematics education to the daily practices of teaching by providing resources, routines, and tasks worthy of students’ and teachers’ time.
