9 Slides is a site I've posted about in the past and is just a wonderful way to take your slideshow presentations to the next level. This site which is iPad compatible is wonderful for uploading presentations and then syncing them to video. This is ideal for teaching a new unit and especially for those giving staff trainings or professional development. Also, a user can track usage statistics for instant feedback.
I highly recommend checking out 9 Slides by clicking here!!!
