As a Language teacher, I highly recommend Alter-Learning games. They focus exactly on the contents you want your students to learn and much more! Apart from that, they can communicate among themselves while playing and interacting. They will also be able to improve their skills in listening, reading, speaking and writing. The fantastic use of visual aids is of great support for them to learn. My students really loved the experience!
