Major Concept: Comparing Numbers
Number of players: Two to four
Materials: the following sets of cards:
0-9, 10-19, 20,29, 30-39, 40-49, 50-59, 60-69, 70-79, 80-89, 90-99
Rules: One player shuffles the deck carefully and then deals an equal number of cards, face-down, to each player.
Extra cards, when there are three players, are placed in the center of the table to be won by the winner of the first play.
The players do not look at their cards, but leave the pile neatly stacked, face-down, in front of them.
Each player turns his top card face-up. The player with the greatest number wins the round and collects all of the face-up cards, and places them at the bottom of his pile.
If there is a tie for the greatest number, the players that tied each turn up another card. The player with the greatest number wins and collects all of the face-up cards.
This play is repeated until one players wins all of the cards, or until a predetermined time limit, of 5 to 15 minutes, expires. A player is eliminated from the game when he loses all of his cards.
Variation: Student can practice Greater Than Less Than with any set of numbers, they can combine sets or play with all the numbers from 0-99.
