Our "Kiss Your Brain" and "Star Jar" reward jars I sometimes reward a student for great thinking with a Hershey's kiss from the "Kiss Your Brain" jar. They LOVE this song from Dr. Jean! At the end of each day, the student custodian inspects our classroom for cleanliness. If the class gets a "thumbs up", then each student receives a Starburst or Tootsie Roll candy from the "Star Jar".
