Well after about four hours I finally worked out what I was doing wrong! Guess its all part of the learning.
After I finally got the hang of it I can understand the benefit of SlideShare. It would be a great tool for teachers to use as they can share their work with others and use other peoples slide shows in the classroom. And I especially like that you can make your own adjustment to suit your class. Overall I think its a great tool for teachers and would really benefit students as their teachers would have access to some fantastic Slide shows.
The above slide show is what I used for my grade six class last year. They really enjoyed it as it was not just paper based and included some video footage on an actual Tsunami.
