This lesson uses some materials off this site but mostly my own. It's a two part lesson, the first lesson is about taking a vacation of the student's choosing, and the second is about sending a postcard from that location. It also teaches students about the different parts of a postcard.

I don't know what the problem is because it is saved in an older format so it should work. I double checked the original and downloaded the one I uploaded too and they both looked fine to me. Just to be sure I will re-upload the slides again but if you are still having problems then I don't know how to help you.
