Greetings,
Educator John Costilla has compiled and posted a list of 100 free web tools which should interest elementary teachers.
The majority of John’s links come from standard web faire such as “Flickr”, “Netvibes” and “Gliffy”, to name but a few. There are however a couple of interesting sites that are new to me (and perhaps to you too) which makes a visit to a site like this worthwhile.
Check it out at:

Enjoy
