I use these tickets to motivate my students to complete their reading logs. Every time a student completes a reading log, he/she is given a ticket. Once a month, we have a "Reading Raffle." I raffle off brand new books I've purchased myself (or with points through Scholastic). The kids LOVE this and it really motivates them to complete those reading logs!
*I'd also be happy to edit the tickets if you have another use (mastering math facts, turning in homework, etc.).
