6. Homework Policy You will receive a new stamp sheet usually on Monday. On the stamp sheet, it will tell you when your homework packet is due. You will staple ALL your homework and stamp sheet BEFORE the bell rings the day the packet is due.

7. Homework Policy You MUST correct all your homework in red pen EVERYDAY to get the 5 points. – It is either 0 or 5 points You MUST answer the student comments on the bottom of the stamp sheet. There might be some days when I collect the homework before your stamp sheet is due. This is because I want to see if you understand a concept. I might tell you before, but not always!

8. Homework Quiz When your homework packet is due, you will also have a homework quiz ( 1 question). You will do this on the back of your stamp sheet! It will ask you “Solve Question # 5 on page 180”. – This is why it is imperative that you correct ALL your homework!
