Combining multiple PowerPoint slides into one deck is a common operation. This is useful to organize your student’s presentations into one presentation.

One way to accomplish this is to use the “Home”->”New Slide”->”Reuse slides” command from your PowerPoint 2010 program, but this is tedious and not really scalable.

To do it automatically, you may want to use an open source program called PowerPoint Joiner.

To know how to use it, you need to take a look at this post http://www.online-tech-tips.com/free-software-downloads/merge-powerpoint-ppt-files/.

I tested it myself, and it works really well.
