Direct modeling addition and subtraction assignment

• Record yourself showing how to solve each problem by direct modeling (ideally using the video on your cell phone and physically direct modeling with the colored cubes). Try to keep your video down to about 10 minutes (or record it in two videos if it's going a lot longer than 10 minutes)
• Use the direct modeling strategy described as being most typically associated with the problem type.
• Upload your video so I can see it. There are two ways you can do it:
  • Option 1: Upload it to Kaltura Media Space (you should be able to get to this from the My Tools menu on the upper right in D2L), and then share it with me by emailing me the link to the video
  • Option 2: Upload it to the D2L dropbox I just made for it.

The problems I want you to direct model are:
