This workshop aims at sharing didactic activities with the use of mobile applications to teach English to age-diverse groups through peer work. These activities have been compiled based on the experience from the project ED-2884 from UCR, Puntarenas, Costa Rica, which receives students from the community with ages ranging from 14 to over 60 years old. It also intends to encourage the audience to modify the activities presented using one of the applications from the workshop so they can adapt it to their own class and realities. All the activities are group oriented; this is, they are to be developed with a partner or two in order to foster cooperative work and enhance communication with students of different ages.
