“Let’s Go Shopping” is a landscape of investigation about economic and financial education framed by the sociocritical perspective of mathematical modelling. The landscape developed as a result of discussions among students from a school in Bogotá about high-interest charges and loans. Our aim was to identify possibilities and challenges in the use of a sociocritical
perspective on mathematical modelling when promoting citizenship education. To do this, we addressed the discussions by the students and considered students’ intentions, backgrounds, and foregrounds. The landscape included investigations of families’ economic conditions, as the students related the mathematics classroom activities to their families’ financial issues.
