This is an ESL classic which has been a staple flashcard game for many English teachers around the world for years.
Divide your class into two teams and then choose one player
from each team to come and stand in the middle of the class
back to back.
Give one flashcard to one of the students and another
flashcard to the other student. Make sure that each student is
holding the flashcard at chest height and facing outward. Also
make sure that each student has not seen what the other
student is holding.
When you are ready, slowly start counting to five.
1.... 2.... 3.... 4..... 5........
As you slowly count, each student slowly starts walking so a gap
grows as you count. On five, shout 'FIRE!!' and each student
quickly turns to face the other student. The fastest student to
call out the other flashcard is the victor and that team wins a
Keep bringing up a new pair until everyone has had a turn.
