You can learn some basic sentences in any language, using international signs.

Step 1: Select your language at the right, and open Lesson 1. There  are several sentences with international signs. Look at the video and try to repeat the sentences with the signs until you notice that it becomes natural for you. 

Step 2: Select any other language on the right and open the same lesson on it. Now, if you try to repeat the sentences with the same signs, you will be able to understand what you are saying.

Step 3: There is a pdf file for every lesson.  Open it and you will see  the sentences with additional vocabulary with the same signs for both languages. A clic on any of those signs will open a page with explanations on how to act the sign. Repeat them in your language and again in the new language.

Step 4: Practice making new sentences. There are three possibilities for it:

-Individual learning: You simply have to do new sentences changing some of the words in them with the new vocabulary. The signs will illustrate what you are saying.

- Learning in group: Try to find some colleagues that want to learn the same language. There is an activity for every lesson that you can make together. You will have to build new sentences using the vocabulary in the same way as before, but now the activity will put you on a more reallistic situation.
