While many children grow up in linguistically and symbolically diverse communities, it is still rare that they encounter an early educational experience adapted to the complexities of their everyday communicational reality. This paper takes an ecological and multimodal approach to a preschool’s book project in a multilingual community. The study examines the web of resources that emerges from activities, actors and their interrelations during the book project. It is shown how multimodal resources emerge when supported by active pedagogical community engagement, and how resources underpinning early childhood literacy cross linguistic and modal boundaries. The paper uses a multimodal interaction analysis to show how the socioecological resources emerging during the project come together in multimodal interaction. Pedagogical potentials building on multimodal resources involving the wider ecology of actors in linguistically complex settings are discussed.
