TITLE:    21  GAME

AUTHOR:   Dan Beaubien, Klamath Falls, Oregon

GRADE LEVEL/SUBJECT:     2-6; Math/Self Esteem

PURPOSE:  TO BE THE ONE TO SAY 21

ACTIVITIES and PROCEDURES:
NUMBER OF PLAYERS:  2

HOW  TO PLAY THE GAME:
ONE PERSON GOES FIRST AND SAYS  THE NUMBER ONE OR ONE TWO.
THEN THE OTHER PLAYER SAYS THE NEXT ONE OR TWO CONSECUTIVE
NUMBERS.  EACH PLAYER CHOOSES WHETHER TO SAY ONE OR TWO
NUMBERS DURING EACH TURN.  THE PLAYERS CONTINUE TO ALTERNATE
TURNS AND SAY THE NEXT ONE OR TWO CONSECUTIVE NUMBERS UNTIL
SOMEONE REACHES TWENTY ONE.

SUGGESTIONS:
AS THE TEACHER I GIVE THE STUDENTS THE CHOICE TO START FIRST
OR THEY CAN LET ME START.  THERE IS NO TALKING EXCEPT FOR
THE PLAYERS. IF SOMEONE FIGURES OUT THE STRATEGY OR TRICK
THEY DON'T TELL. I CHOOSE THE PLAYERS.

TYING IT ALL TOGETHER:
THIS GAME TEACHES THE MATH CONCEPTS OF: SETS, DIVISION OF
THREES, ADDITION AND THINKING SKILLS.  ALSO USE TO BUILD
SELF-ESTEEM AND MAKE LEARNING FUN.
