In our multilingual project, twelve pupils who are learning English in a Greek school (Western Greece) and the ones who are learning Spanish in a Turkish school (Istanbul Area) are going to develop their eTwinning collaboration through Web 2.0 technologies in order to create and exchange Christmas cards in four languages (Greek, Turkish, English, Spanish). Each student will have a penfriend from the twin country to exchange personal info and their Christmas cards in pairs by airmail. At the end, our multilingual students prepare and exchange videos with Christmas songs and Christmas greetings in all four languages.
