The project C.L.U.E. (Collaborating and Learning United by English) is designed for the collaborative development of activities related to common topics of the partners’ English Language curriculum (personal identification, Halloween, physical description, Christmas). The “clues” are outlined around common themes from primary education syllabi, giving students the opportunity to develop their English language and integrated skills in motivating and enjoyable ways. The “clues” aim to broaden the students’ competence and confidence they need to enjoy learning English.
