Great node! In fact, one of my first nodes on perlmonks was about teaching perl to children. You might want to review it: Teaching Perl to Children
One resource not mentioned here is an effort to teach Java to children.
Like many others here, I was introduced to programming when it was a new and exciting field. Computers were mysterious boxes that few understood. Today, children carry around small games that have more processing power than 200 lunar modules from 1967.
On a whim, I attempted to verify my statement above. I found the specifications for an Apollo Guidance Computer but the design is so old a proper comparison is really not possible.
As is often the case I did find some amusing subjects along the way including this Virtual AGC project. It is amusing to see the actual code compute a checksum, time events, and display a few simple calculated results used by Apollo astronauts during landing.
The first dog barks... all other dogs bark at the first dog.
