Happy Independence Day!
The 4th of July commemorates the signing of the Declaration of Independence... by those who have come to be known as "The Founding Fathers." This is a great day to read the Declaration of Independence. (For fans of audiobooks and all those interested in hearing/listening, it is read aloud here.)

While July 4th is related to the Declaration of Independence and September 17th commemorates the US Constitution, both are founding documents. Parents on this forum may be interested to know about the annual contest sponsored by Constituting America... July 4th is a great time to begin working on an entry due on or before September 17th.
