I used this game last year with great success with 1st grade middle school students, and this year I've improved it with some animations (the pictures will disappear after you use them).
Just a simple bingo game to refresh/check some basic classroom vocabulary and basic sentences in English. If your students don't understand every slide has a Korean translation you can click.
Print the 'BINGO' sheet for all your students and one extra for you to cut up and put in a bucket to draw items (instead of numbers). You can get the students involved by having them pick and call out the item.
Every time a student gets 5 in a row and shouts 'BINGO' I give them a sticker for their sticker reward sheet (every 5 stickers they get a small candy or prize).
Game takes about 15-20 minutes including demo and instruction time.
