The present approach describes the work carried out by two educators in two different geographical, cultural, and linguistic contexts: Colombia and the United States. As educators, they share a) the responsibility of preparing future preschool and primary school teachers, and b) an interest in creating educational experiences that foster an expansion of perspectives on what it means to be a teacher. The authors propose a collaborative framework and suggest its implementation in teacher education. The proposal describes three years of collaborative work creating spaces for future teachers in an Early Childhood Education program in Colombia and a teacher education program for elementary school teachers in the United States to interact and collaborate with each other on the development and implementation of various educational approaches in mathematical contexts. The proposal suggests the design and implementation of a framework for collaboration aimed at transforming educational practices.
