Teacher Vision – database of lesson plans
Litebrite – remember the old litebrite toy? Now you can do it online. This can be used as a reward for students.
What2Learn – make your own games and no downloads needed.
Build Your Own Jeopardy - A jeopardy-like board creator that you download. I love to use this in the classroom and the students love to play it. Great way for them to study for exams.
Graphix – children can make their own comic books. There is also a teacher guide on how to use graphic novels in the classroom.
