1.I don´t have a favorite game, but adapted one that has worked very well in certain topics, this in the "hot potato" and it is only in order to promote the participation and the person who has the "potato" will take a card; whether a topic as verbs, adjectives, etc... and with "mime" students have to guess. The student who guesses will be accumulating tenths extra to average.
2. I use a lot of texts with artwork and texts of interes, once they have read, they fill gaps or identify is the sentence is true or false. Then, in couples give their reasons in oral way, and this way I promote the motivation and communication between them.
