ToonDoo is a very user friendly web based application that allows you to create cartoon strips and even cartoon books. The site is designed to encourage participants to create new strips, share their work, and discuss cartooning. What a great way to get students involved in the writing / digital story telling process. The Toon Creator is full of backgrounds, character, props, and other useful tools to aid in creating your masterpieces. I would say that the site is certainly appropriate and easy enough to use for elementary students but is entirely appropriate for older students as well. What a find :)

The Comic Creator invites students to compose their own comic strips for a variety of contexts (prewriting, pre- and postreading activities, response to literature, and so on).

This versatile tool can be used by students from kindergarten through high school.

The Hot Potatoes suite includes six applications, enabling you to create interactive multiple-choice, short-answer, jumbled-sentence, crossword, matching/ordering and gap-fill exercises for the World Wide Web. Hot Potatoes is not freeware, but it is free of charge for those working for publicly-funded non-profit-making educational institutions, who make their pages available on the web. One of the things that I really like about Hot Potatoes is it's seemless integration with certain Learning Management Systems. I use Moodle quite a bit, and you can include a Hot Potatoes activity right in the Moodle course.
