Attached are the big bucks I use in my class a reward. There are ones, fives, and tens. I print each value on a different colored piece of paper. I will pass out the money as a reward for students who do something great in class, those who return an important letter the next day (progress reports, report cards, etc.), and for many other reasons. Students can then trade these in for coupons they can use in class. Students are very motivated to earn their big bucks and are always excited to spend them. It also helps students work on counting to find the total money they have and also for finding change when they spend a certain amount.
