Here is a list of activities useful for practicing various dialogues when you can't think of a game that imitates the real life use of that target language.
These games/activities are good to use in elementary schools when you have a basic question and answer dialogue you want the students to practice and want to make it a bit more fun than repeat, repeat.
Activities for practicing dialogue
Race down the rows of desks using dialogue between students. First row for everyone to speak wins.
See the full description of row racing.
Using interview worksheets, set the goal for students to walk around and communicate with their classmates.
See the tips on making and using worksheets in English class.
The bomb game
The bomb game adds the thrill of a countdown to practicing dialogue in groups.

Wall to wall (speak up challenge)
After practicing the dialogue, this activity will challenge them to speak up loud and clear.
