Each team adds one or more words in the table in the nationa language. Other teams are supposed to write the translation, but not only text but they should add the audio too. We can use the tool called Vocaroo (http://vocaroo.com/). It is very easy to use it. Open the website, click on record. After you can copy the URL of the record and put it in the table. Here one videotutorial from Youtube.
If you don´t understand the word, you are supposed to write somebody of the team and ask him, what the word means.
