Oh, I just love the magic of stickers!  I let my piano students put a sticker on their song after they have learned it and passed it off.  They go absolutely crazy over the stickers.  One student chooses a theme for each day: “All of my stickers today are going to be red.”  Another wants to get the biggest ones on the sheet.  Others are obsessed with what other students are using for their stickers.  And they go absolutely BONKERS when I pull out a fresh, untouched sheet of stickers!  They are so easy to please!  What other simple, inexpensive ideas do you use for motivation?
