Classroom Motivation System- Raffle Tickets

A simple classroom motivation system is a weekly raffle.  It's pretty simple.  I have a bucket for each class, and raffle tickets.  Students can earn raffle tickets for almost anything.  Kahoot, Gimkit, turning in homework, volunteering in class, etc.  Every Friday I raffle off about 10-15 pieces of small candy and some sort of grand prize! A very simple way to reward classroom engagement and the students love it.  I usually stock up on candy after Halloween, Christmas, Easter, when everything is marked down! What do you do in your class?
