Their teacher, Lauren Swanson, introduced them to the musical's soundtrack as a way of teaching history.

Students at Carlisle School in Danville, Va., performed the Broadway play’s opening song, "Alexander Hamilton," during their class graduation.
The critically-acclaimed musical has helped teach the class a valuable lesson about America's early days.
“I think they will do very well in their high school U.S. history class,” their teacher, Lauren Swanson, told InsideEdition.com.
When they heard the music, the kids were hooked, and Swanson was astounded by the heavy amount of knowledge they absorbed as a result.
“My students were immediately drawn to music and wanted to learn more and more about Alexander Hamilton and his legacy,” Swanson said. “This obsession with Hamilton turned into a yearlong study — I’m still amazed at how much information they soaked up in their little brains."
Swanson said she had the students perform their favorite song from the play as a part of the latest viral challenge, #Ham4All, where participants can upload a video of themselves singing a song from the musical to win VIP tickets.
The contest has been set up by the play’s creator Lin-Manuel Miranda.

For a donation of $10, the students were all entered to win tickets to see the play in person through The Immigrants: We Get the Job Done Coalition.
As a nod to a lyric in the song, Miranda started the charity through the non-profit Hispanic Federation to raise money and awareness for immigrants, refugees and asylum-seekers.
