• Lesson
• Work on the Review in your group.
• You will get a group grade for working together.
• Everyone works on the same problem together. In
  other words, do not go on until everyone in the
  group has done and understands the problem.
• Are they supposed to copy your work? Nooooooo!
  Help each other and explain how to do it. Thats
  what the grade is for.
• If you are off task or go on and leave the
  others, your personal grade for the day will be
  lowered.
