4th of July and Independence

The other day the boys and I were having a discussion about why we celebrate the 4th of July. It led to us defining what independent means. Here are some of the things Mr. O said he could do independently:
Play with toys
Read books
Make my beed
Brush my teeth

Here are a few thing Mr. R though of:
Put away clothes
Clean up toys
Take a bath

Seeing this list makes me realizes how fast they are growing up! What other aspects of Independence Day would you try to teach young children? I think we'll try to discuss freedom next.
