Divide the class into different groups with 3-4 members. One member of the group will act as the game master then the rest of the members will be the players. Each group will have one deck of card (with 36 cards)
The game master will say the words in the pattern - Santa, cookie, elf, candy, snowman - and at the same time flip a card from the deck. If the word and the picture doesn't match, the game master will say the next word (following the order: Santa, cookie, elf, candy, snowman) and flip a card. If the word matches the card, the players will race to grab the card. The first one to grab the card, gets every card that has been laid down.
But there's a bonus card: Grinch. If that card appears, the first one to grab it, gets all the cards that each player has already grabbed.
The player who has the most number of cards, wins.
After one round, the group can decide who wil be the next game master and so on...
