Class, I read and graded your last assignment.  A lot of you improved with the explanation as to why you took a certain position.  That is great but some of you show room for improvement.  You get an A.  Now don't rest on your previous grades.  There still is work to do and room for improvement.

Here's this week's assignment:

This week I am going easy on you.  You will only have to list the bands for each decade however if you want extra credit you may tell me why you selected that particular band.

OK, class, it's time to get to work.
