I imagine there will be something similar on line now for the 2006 Olympics.
Here is a link to the lesson plans for the 2002 Olympics. You can
adapt these to this year.

Lessons are for grades 4 through 8. Topics deal with character
development/heroes and world peace.
I would be interested in adding your Olympic lesson ideas to the page
on Art about Sports.
