Clarification on class absence and forgetting Instrument

Band is both an academic and a activity class.  So when students are absent or forget their instrument the student is not able to participate.  They do not gain knowledge and the other students also miss from their not contributing to the band on that day.  So when a student misses band for illness or a school activity they will receive a zero for that day, however they may make up the full 100 points by practicing for 60 minutes and bringing a signed note from the parents, within a week.  A 50 is given when students forget their instrument.   Again the 50 points may be made up by practicing for 30 minutes and bringing a note from parents within a week.  This is not meant to be punitive, but to encourage progress to be made by all.  In addition to see how many are reading this blog, I will give $5.00 to the 5th student who emails me that they have read the blog.
