This is a partner activity/game to help students practice the -er and -ir verbs from Chapter 4 in ¡Así se dice! 1. Students play Batalla Naval (designed like the real game Battleship) in pairs and must use the correct grammar/know what they are saying in order to get information about their partners' ships (students sit next to each other but set up a barrier so they can't see the other's paper - they mark down where they have been hit and where they have called their partner's ships on their own paper. First to sink all their partners' ships is the winner). I usually explain this activity in English the first time we play in class, especially for students who have never played Battleship before! One page double sided activity - on a Word Doc so easy to edit.
