Hi, I'm working on a presentation that will cover some basic calculations. I will be presenting to a small group of people and would like to provide the formula and have them work the calculations themselves and give me the feed back that I will then enter on the screen for all to see.

Rather than have to switch back and forth between modes, I would like to have a "notepad" on the slides themselves that will let me enter their responses. Any ideas on how I can achieve this? Thanks.
