Come in, please.
Close the door, please.
Look at the board.
Eyes on me.
Stand up, please.
Sit down, please.
Be quiet.
Raise your hand.
Clean the board, please.
Turn on the light, please!
Turn off the light, please!
Listen to me.
Listen and point!
Listen and repeat!
May I go out, please?
May I come in, please?
