This case study of multimodal pedagogies within an intergenerational (IG) art class addresses questions about the learning opportunities that were created therein and what the fixing of participants' ideas within a semiotic chain said about their facility with communicative modes and media, interests, and identity options. Key findings include: when compared to the adults' work, the children's use of media was more elaborate, experimental, and less inhibited and their designs more complex; the content of the children's communication was multifaceted, and future-looking while some of the adults' were constrained by limited identity options related to their position in the life course; and the class's multimodal pedagogies provided occasion for the exploration of modes and media with support for working through key communicational decisions.
