During the spring of 2020, INDIRE created Spaesi, an online training workshop that proposed teachers to use the inventive techniques of the Grammar of Fantasy (1973) to deal with the difficult situation of quarantine with young students (kindergarten, primary and lower secondary school) The initiative, on the occasion of the centenary of Rodari's birth, was aimed at stimulating and supporting collective writing experiences of fictional stories, tales, poems and rhymes during the distance learning period. The article analyzes the documentation of the experiences sent by over seventy teachers who participated in the workshop, taking into account the digital tools and writing process, the "participation rules" developed by the groups, in order to identify a repertoire of cooperative techniques for remote work, even between different classes. The expressive and textual forms practiced by the classes are also analyzed, as well as media used for the realization of the texts, to understand how curricular and cross curricular learning is affected by the practice of collective writing in a digital environment. Finally, the analysis identifies some recurring themes in the texts developed by the classes.
