In my classroom I use a ticket system to reward my students. They can purchase these coupons to use in my classroom for various amount of tickets.
This is a cheap way to provide student prizes that kids actually want!!!
This is a zipfile of the following coupons:
Turn in a classwork the next day (extra time pass)
Free homework pass
Chew gum in class pass
Late homework pass (one day late for full credit)
Locker pass (I am really strict on my students going to their locker because I believe they need to come to class prepared, so this is very popular with my kids)
