Constitution Day is September 17th. Here are a few activities and sites as you plan for this day.
We The People (Constitution Song)
Schoolhouse Rock -- Preamble
Reader's Theater- Creating the Constitution
Constitution Day Mini Unit This indicates it is for 1-3rd grade, but I like the tree map and think it could be used for older age groups-- especially if you are using the constitution as a primary document!
The US Constitution Mini book
Constitution Day Poster Contest
As I find more activities-- I will add them. :)
