This year, I will have one grade from K4-1st and 2nd-5th who will be the Super Musician class. At the end of each class, the older students will be required to answer questions. With each correct answer, the students will drop a pompom in their own grade's jar. The younger students will be graded on a scale for proper behavior. The first grade to the top of the jar wins! They can have the pompoms taken away, however, with poor conduct, but I doubt that will be a problem!
In addition, I will add one grand student each month to the grand staff! To choose this student, I will secretly pick a rule that must be followed. During class, I will monitor which students keep the rule. At the end of the month, one student will be chosen from those who followed the secret rule and will get his or her name on the grand staff for the following month along with a treat.
