In the past, physical barriers such as geography and distance limited global communication. In this paper, we explore how young children in immigrant families engage in transnational literacy practices. Specifically, we explore the transnational funds of knowledge that result from those experiences. This three-year longitudinal collective case study involves ten children from immigrant families who have come to the United States from around the world. The students entered the study in four-year-old kindergarten, grade 1 or grade 2. Each year, we collected observations, spoken data and student-created artefacts (e.g. writing samples, maps, photographs). Data sources were designed to highlight the various spaces that the immigrant families occupy or have occupied over time (i.e. home/neighbourhood/ school; native country/country of residence). Our reading and rereading of coded data across the sample led us to focus on families' digital transnational practices and children's transnational awareness. We argue that these funds of knowledge should be recognized in classrooms and schools and that they have the potential to contribute to the nurturing of cosmopolitan perspectives for all children.
