Super miming
Student A leaves the classroom for 1 minute. The teacher gives 1 card to each player remaining inside. When Student A comes back, the players start miming their emotions simultaneously. They stop upon the teacher's request. Student A tries to remember everybody's emotions.

Back to the board
Student A should be sitting with his / her back to the board. The teacher sticks a card with an emotion to the board (so that Student A couldn't see). Everybody starts to mime this emotion, Student A tries to guess.

Guess my card
