Even if the new technologies are only one of the instruments that a teacher can use in his job, they can give positive stimuli to learn and to teach new contents and create competencies, above all in the CLIL methodology; in fact, to learn a new language asks to the students to be creative, collaborative, organized and to have a critical thinking and the use of the apps or webtools can help in this path

Vocabulary.co.il are very interesting for me. 

Rewordify allows to work on the text and to make it more simply, replacing the difficult words with easy words. Also, with this webtool you can create many kind of exercises on the text, allowing to deepen the reading. There's, also, the possibility to listen the pronunciation of the words that there're in the text. In my opinion this webtool is more indicated for a hight school level.

Wordsift allows to visualize the words that are in the text, creating colored clouds. It is a webtool useful to enrich the work with pictures and it can be used by everybody.
Finally, Vocabolary.co.il is a platform where is possible find many games and exercises on the English vocabulary: for example Letter Blocks, Match Game, HangMouse. In my opinion this webtool is very right for the primary school.

Instead, to build exercises and games about English vocabulary you can use LarningApps, a webtool very interesting.
