Math busking is a way of inspiring an appreciation for math by making it more accessible and inclusive to a wide range of people. Infused with playfulness, energy, and enthusiasm, math buskers provide large scale, hands-on activities that invite audience participation and engagement with mathematical ideas. Watch our video of teachers in Bev Caswell's AQ Course math busking on the streets of Toronto.
