I use this bingo card as a reward system throughout the year and my 7th grade students love it! They earn stamps on a square for good behavior and achievements and when they get a bingo, they draw a rewards coupon. I let them use the same card until it's full of bingos, so the more bingos they have, the more chances they have for another one. When they have a black out, I let them draw again and I'll give them a brand new card. Some coupons that I use in my class are:
+5 extra credit
Candy Pass (I give them a small candy bag and it's their favorite coupon)
Teacher's Assistant (2 weeks)
Headphone pass (for independent work)
Pick a Prize
I will have my coupons posted soon!
