What do you do when your 8 and 5 year olds want to build Web sites and you have little knowledge to impart beyond some basic HTML?
Here's a look at some of the programming resources for children that came back. They are in order of popularity among the folks I queried. These sites looked interesting to children as well as a few parents.
Scratch. This effort from the MIT media lab is intuitive, animated and can land a kid into programming.
Lego Mindstorm was also touted as a fun place to get started on robotics.
Shoes. Shoes is an effort built on top of Ruby and was built with kids and students in mind. Hackety Hack is another Ruby site.
Lisa Explains features HTML explanations in a colorful format.
Markerbot encourages kids to tinker.
For older kids...
SQL Zoo is an effort to teach high schoolers how to query databases. The overall aim is to teach kids how databases are structured.
Play Framework is an effort as simple as Rails, but built on Java. It's a good introduction before jumping directly into something like Python and Ruby.
