This article reports on a qualitative case study involving pedagogical innovations grounded in culturally and linguistically inclusive approaches to curriculum. In this project, kindergarten children were supported in collaboratively authoring Dual Language Identity Texts. Our findings suggest that as family and teacher conceptions of literacy were extended beyond traditional monolingual print-based literacy, home literacies associated with complex transnational and transgenerational communities of practice were legitimated through their inclusion within the school curriculum. This process invited family members to take up roles as expert partners in children's biliteracy development. Further, conditions were fostered for parents to consider and articulate their beliefs and values vis-à-vis their children's multiliterate practice and participation within these multiple, transnational communities.
