The teaching of foreign languages emphasizes communicative and intercultural skills; however, Colombian education often neglects local cultures, leading to cultural alienation. This research aims to investigate the role that a digital booklet, designed from a decolonized perspective, plays in the EFL learning process and the development of intercultural communication competence of a group of young learners. This research follows a qualitative action research design and the participants are four children from Puerto Gaitan, Colombia, who took EFL lessons online, and whose parents are active members of a social foundation located in the same municipality, which is interested in fostering their communicative skills in the target language to help them become cultural ambassadors of their region. The instruments used to collect data were transcripts from the video recordings of the lessons, field notes and the students’ productions. Findings show that the booklet played the role of a motivational source, a facilitator of context and language and a provider of interaction among cultures by means of its features and activities. Likewise, the use of the booklet fostered the children’s development of intercultural attitudes, knowledge and skills, which represent the basis of their intercultural communication competence.
