Math Assignment February 1st

Hello 8th graders.  Sorry I am still sick.  Please complete the assignment listed below. In your notebook,
label each section and write the answers neatly in your notebook.  This must be finished for Wednesday.
You should have time to complete this in math class. If you finish early you may play the FACTOR game.
If you are the odd man out, play against the computer.   If there is an odd man out, the teacher should
remind you to rotate partners.  Remember that the person on the left stands and moves one place to
the left.   (Only if the Factor Game does not work...then play the Product Game.)
