At the end of each week I draw one ticket (sometimes more depending on what I think will work best for that week). Whichever student gets their name drawn, gets to pick one of our classroom rewards. I have lots and lots of reward coupons they can pick from. Here's a small sample...if you'd like to see all of the coupons, I have them up on TeachersPayTeachers. There are 35 individual rewards and 10 class rewards, plus some blank coupons, too.
Besides homework coupons, the other way to earn a reward coupon is to have your name drawn off our BINGO board. Our BINGO board has 100 spots. Once the board is filled we draw to see which student will earn a reward coupon of their choice. Students can get their name on the board for just about anything...showing kindness for another student, finding a vocabulary word in their independent reading books (and being able to define it or use it properly in a sentence), finding a spelling word in their independent reading books (and being able to spell it properly), dressing up for a spirit/color day, and lots more. I look for reasons to let students sign their name on the board. We pretty much fill a board every other week or so. In addition to getting individual names on the board, they can also get 5's (because they're in the fifth grade) on the board. The earn a 5 by being complimented by another adult in the building, getting 4 checks in PE (a classroom management system our PE teacher uses), working quietly when they are in small groups, etc. Again, I look for reasons to let them put a 5 up on the board. If a 5 is selected, then the entire class gets a reward. Here are what some of the BINGO charts I've used look like...
