I remember seeing a similar book. I think this was it http://www.helloruby.com/ which seems to be more professional/educational, I think there even are some work-books?
Hello Ruby is beloved by my daughter, and yes, teaches the concepts without ever really mentioning computers in much depth.
I've been looking for a book like this since I had my first kid three years ago!
Thanks! We wrote the book after searching for a couple weeks for a book like it. I actually ended up writing a list of all the different programming books for babies and toddlers [1].
Hope you like it.
