This project is aimed at students aged between 10 and 16 years and consists of creating, a gift box (cylinder or prism) using cardboard to celebrate the festive season of Christmas. The students plan their geometrical construction. In addition, the box will also be decorated with geometrical stars and other items. As a complement to the creation of the present box, a postcard will be prepared describing the traditions of this festive season (food, festivities, recipes among others), as well as a video with a song alluding to the Christmas theme of each participant's country. In the end, all the participants involved will be able to connect through Etwinning to share their projects and experiences through the creation of a quizz and a magazine, as well as get to know each other virtually through this platform.
