This tool can collect a series of web sites and present them in a sequence with your text commentary. It's similar to the Nethernet game but not called a game. Quite useful if you want to show just a range of sites with your comments on each. I suppose I could have used it for this but I didn't.

Here's an example created by a teacher to help pupils explore Ancient Egypt. There are lots more on the site too. In many ways, just getting the lists of links makes this worth a visit!

There's another about Web2.0 for kids which may even give me more ideas to feature here. (From a first peek, though, quite a few weren't free which was disappointing.)
