UPDATE: Since this tutorial was created in March of 2012, Prezi has substantially revised their interface. The Graphic Organizer within the Prezi has also been updated so that the text within it may be edited, and arrows and boxes containing the questions can be deleted or added. A new set of tutorials will be created to reflect these changes, but the basic procedures are largely unchanged, and the tutorials below are still useful.
There is a new version of the Template, now linked below and here. This link was added February, 2013.
