Here is your challenge. 

 Today we have several people absent.  I need you to create a Powerpoint to help them understand the concepts that they missed in math.  Do you think you can do that?

 Open up Powerpoint and create 5 slides to explain to someone who was absent how to add large numbers.  Make sure to use examples!!  You can use your work from your PW workbook to help you come up with problems.

 Good Luck!
