This game is good enough for warming up before the lesson begins. You only need five or ten minutes to play it with your students. Beside that, this game doesn't need much preparation.
The game should start by your self as an example. "My name is John, I am Joyful." Then ask your students to find an adjective which the innitial is the same as the first letter of their name.
Let your students think in one minute then start the game by calling out names through present list or ask them one by one.
The following are some more examples:
Ani - Awful
Brian - Bold
