I learned a couple of very important things this weekend while I created a presentation for nearpod. First, if you start with a power point presentation, you have to upload it and then clone it before you can do anything with it. You cannot take the slide and make it interactive. You have to create a new slide to set up to draw, create a poll, create a quiz, or add a open question or web link. When I decided to add a draw on it slide, I had to take the original power point slide, convert it to jpg or png and then import it.
Fortunately, I found a free website Zamzar who will convert files in one format to another and e-mail you the converted file. Once I got the file back, I inserted it and I am ready. The others are fairly easy to figure out and use as you just add a slide, determine which type of activity it is and get it set up.
Secondly you can build the presentation from scratch and just set up the slides as you need them. I am not sure which method is easier but Nearpod is not too hard to use. They do have a content tool user guide which helps tremendously. It was due to the users guide I learned I needed to clone the presentation first.
Tomorrow I will present this and see how it goes. I would have done it today but we have an inservice.
