Despite the growing importance of intercultural education, literature is still lacking in related research with young learners. This study reports on a yearlong university-school collaborative research project that aimed to promote students' intercultural competence and critical bi-literacy skills through their exploration of the issue of children's rights. Grounded in the critical perspectives of intercultural pedagogy and dynamic bi-/multilingualism, the two collaborating Grade 3 teachers engaged their students in critical inquiry of children's rights in both English and French. Through a range of hybrid translanguage literacy practices and experiential learning activities, students came to understand what children's rights are and appreciate the importance of solidarity, equity, and compassion. Apart from highlighting some activities developed during this project and the impact of the activities on student participants, the study also attempts to critically reflect on some of the challenges in conducting intercultural education with young learners, in particular their emergent but conflicted understanding of other cultures. Further, the study speaks to the issue of how such an important education can be practiced in a non-reductionist and non-simplistic manner yet still be accessible to young learners.
