I simply created a slideshow using PowerPoint, then saved it as a PDF. Next, I uploaded the PDF file to my Dropbox, then sent the file to iBooks once I had it on the iPad.
It sits neatly on my shelf.
Here is a PDF of a slideshow about a war memorial that might be useful for teaching about Australian history or Anzac Day.
The pages display very nicely on the iPad and it will be great that my students will be able to review the information on their own after I introduce the slideshow to the class. They are going to make a concept map about the War Memorial, so the iBooks will be another way for them to access the information without me having to print out pages of black and white worksheets. They can zoom in and out on the photographs so easily. This will be a great way for them to be able to access the sources themselves so they can pose better questions.
I'm so excited - I might go and make another one!
