Trick or Treat Party Game
Use a cookie cutter shaped like a pumpkin and trace 12 pumpkins (or the number of guests who will be at the party) on orange construction paper, cut them out. Note: It is important to try and make these the same size. Then take 11 of the pumpkins and write Trick on the back and on 1 write Treat. Adjust the ratio of Tricks to Treats if needed.
On the Trick pumpkins write a silly thing to do like walk like a spider, or cackle like a witch, or flap your wings like a bat, dance like a fairy, walk like Frankenstein and more.
Now put all the pumpkins in a plastic witch kettle and have each child draw one out. If they get the treat one then let them choose a treat out of another bucket or award them a prize. If they get the trick they have to do what it says to earn the treat. Or for additional fun you can continue to make them do additional silly things until they pick out a treat.
