Review Game

 We will be playing a game similar to Password.

 Move all the desks into a big circle.

 There will be 2 teams.

 You will sit in a circle, alternating team 1, team 2, etc.

 The object of the game is to answer questions quickly and pass the deck to the other team.

Review Game

 There will be a deck of index cards with Chapter 13 info on them.

 You will need to give clues WITHOUT SAYING ANY OF THE WORDS ON THE CARD so that your teammates can guess the vocab. word, definition, phase, etc. on the card  Once your team has the correct answer, pass the deck of cards to the person on your left.

 The other team then does the same process of giving clues/guessing what’s on the card.

Review Game

 There are some cards that say “reverse” on them. If you get that card, simply pass the deck back to the person who just gave it to you.

 There are some cards that say “wildcard” on them. If you get that card, you can choose someone on your own team to give the deck to.

 There are some cards that say “lose 1 point” on them. If you get that card, your team will lose a point (which is a good thing!) and the clock will stop.

Review Game

 There are some cards that say “free pass” on them. If you get that card, simply pass the deck on to the next person.

 Some cards don’t have anything to do with Chapter 13 or even this class…

Review Game

 If the person with the deck doesn’t know how to give a clue or doesn’t know what the card means, they can ask the teammate to their right.

 If that person can’t help, then that team will be out of luck.

 After 1-3 minutes, the timer will run out and the team that’s holding the deck will receive a point.

 Each person on the team with the LEAST points at the end of the game will get $1 mole money.
