Hi Sharon,

Neat activity. 

I do want to point out a couple of primary sources that you may want to reconsider.

This one on Paul Revere is not actually about Paul Revere, it's about William Jennings Bryan and dates to 1904.  https://www.loc.gov/item/2011645534/

Technically, this one is not a primary source because it was painted by N.C. Wyeth, who was not born until long after Revere was dead.   https://www.loc.gov/item/cph13631/

This one on the French and Indian War is a secondary source as it is from 1855, 100 years after the event.  https://www.loc.gov/item/2006691550/

This cartoon was published in 1929 and deals with taxes in 1929, not prior to the Revolution, so may be confusing for kids.  https://www.loc.gov/item/2016678849/

This is a lovely magazine, but also not a primary source. It was published in 1936.  Mount Vernon was a house museum by that time and many things like this were printed specifically to stir nostalgia and patriotism and weren't necessarily accurate history.  https://www.loc.gov/item/musdcmicon.0398/

There are some excellent primary sources in these collections at the Library -- and all can be downloaded.

The Museum of the American Revolution has images of artifacts (primary sources), including General Washington's field tent, that your students may find fascinating along with the images and documents.  https://www.amrevmuseum.org/learn-and-explore/collection

Thank you for sharing!
