I have seen the same game called "robot" and played with small kids. The "robot" was somewhat forgiving, because otherwise there was no way that the kids could have gotten the sandwich made.
The kids found it funny, but I'm quite sure that the actual point sailed over their heads.
I don't know... sure the kids may have missed some of the subtler points, like decomposition and atomicity. I bet though, that they now have a pretty good memory "hook" for robots being silly creatures that are a little dumb and need lots of very careful instruction. This is a good fundamental bit of understanding for later dealings with computers.
