In small groups, students take turns asking each other what time it is. One side has a time (on the hour) and the reverse has a +,-, or 0 point value. Only the asking student may see the back of the time card. If the student wants the card, he/she answers. If doesn't want the card they say, "I don't know" and the asking student keeps the card. The student with the most points when all the cards from the center are gone is the winner.
