Each class receives a Bingo card which I hang on the wall so everyone can see. Classes can earn BINGO stamps on their class BINGO card multiple ways. (everyone is on time, everyone turned in their homework, the entire class has their supplies, everyone participates, students are working productively, etc.) During the class period I count how many BINGO stamps they earned for the class. I have a cup of 100 popsicle sticks numbered 1 though 100. I randomly pull out popsicle sticks depending on how many stamps the class earned. I place a stamp on the BINGO card over the number(s) written on the popsicle stick(s). First class to win BINGO get a prize. Then the game starts all over again and I print out new BINGO cards. Print BINGO cards on 8.5x14.
