The talk about Lego's reminded me of a summer class Miami University(Ohio) has for kids. You sign up and get the Lego's sent to your home, you log onto the computer and do the class at home. The recommended age is 8 and up, but I didn't see that as mandatory. Here's a link, Miami University

Since it's done at home it may be open to anyone in cyberworld. Other universities may offer similar things.
