Steve,

That's a good idea. Last year, I did something similar. My daughter  
asked me
to come to her second-grade class to talk about "the big computer" we  
are
building, which is perhaps a younger group than you had.

Some colleagues and I came up with the following:

The teacher handed out copies of one of the classroom books, so
all the kids had the same book. Each child was assigned a page in
the book. We did a couple of different problems. First, distributed
search: who can find the word "blue"? Can the kids (parallel) do
it faster than the teacher (sequential)? Second, distributed counting:
how many times is the word "sky" in the book? Again, race the
kids against the teacher.

I don't know how much they remember about it, but it was fun.
