How to play:

Sit the children down in a circle. Explain them that they have to be quiet to play this game. Then either you choose a Halloween word to whisper into one of the kids' ears or if you prepared written cards, let them pick a card.
The first child has to whisper this Halloween word into the ear of his/her peer who is sitting next to him/her. This goes on until it reaches the last child who can say it out loud. Let's see how well they could pass the word on. :) :) :)
If you are the one who choose the word then start with an easy one and see how your students manage. In case they are good at it you can tell them harder and harder words.
Teaching older children or having more advanced students, you might want to try the game out with whole sentences.

The house is dark and spooky.

I can see a glowing pumpkin.
The ghost says, Boo!!!
A scary skeleton is standing by the door.
