CS Unplugged (http://csunplugged.org/ http://csunplugged.org/) has some good resources for teaching CS concepts without needing a computer. I'm not sure how easy they would be to do at a distance, but you might find some aspects that would work well. Bootstrap World (http://www.bootstrapworld.org/ http://www.bootstrapworld.org/) is a curriculum for teaching CS and Algebra while making a simple graphical video game using Racket (similar to Scheme). You can do the exercises using Dr. Racket IDE or by using a web-based IDE (http://www.wescheme.org/ http://www.wescheme.org/). You also might take a look at Picturing Programs (http://picturingprograms.com/ http://picturingprograms.com/) and How to Design Programs (http://www.htdp.org/ http://www.htdp.org/). Both of those may be more advanced than what you would want to start with, but they are both focused on teaching computer science concepts more than the particular language and both are aimed at beginners without any background with code.
