My adult students look forward to receiving stickers for work done well or for putting extra effort into their assignments. Stickers are inexpensive, can be fun and encouraging, and are easy to use. Many of my students group their stickers on visually prominent items, such as their ID badge or on a notebook cover. These collections act as a motivator and as a conversation starter for new students who ask, "where did those come from?" Stickers have often sparked positive competition within my student population.
