Slides Carnival

 Google Slides is a wonderful tool to use with students for presentations.  However the selection of created templates is rather limited.  You can of course go to the plethora of templates @ Google Templates however they tend to be more of the same.  Slides Carnival has created professional looking templates that are very easy to use.  A few clicks are you are on your way to a professional looking presentation with all the unique slides many have expected from Microsoft Powerpoint.  In all my research the presentations remain totally free.
