Woohoo! Awesome! Last 2 years back I had to give a presentation to some 5th graders for my bio class. I decided to do it on CP and it was a big hit! I've also presented to my 5th grade class.
Don't you just love their youthful enthusiasm? A lot of the time you can get some really good questions and comments out of 'em! Not to mention it feels nice to spread the knowledge to the youngins!!
Congrats on your success.
