I use these reusable coupons for motivation in the classroom. You could sell them in a "class store" or you can give them away in the class for outstanding effort, participation or any other reason you can think of that motivates your students.
This coupon entitles the student to borrow a pen from me for the day. I'm really amazed just how many kids forget basic supplies! I guess this coupon was the most surprising all of the coupons that I offered!
I had 6th graders and they LOVED the coupons!
