This article presents two lessons. The first one is "Carved in Stone: The Preamble to the Constitution" by Steven S. Lapham. In 1937, the Works Progress Administration (WPA) commissioned artist Lenore Thomas to create some sculptures for the planned community of Greenbelt, Maryland. Part of her work consisted of bas-relief friezes on the side of the Greenbelt Center Elementary School. This lesson uses the friezes to study the Preamble to the Constitution. The second lesson is "The Diary of an Underground Railroad Conductor" by David Reader, Beth A. Twiss Houting, and Rachel Moloshok. The website Preserving American Freedom is a digital history project created by the Historical Society of Pennsylvania with the Bank of America that explores the concept of freedom through 50 historic documents. This lesson explores how students may use excerpts from one of these documents--William Still's "Journal C of Station No. 2" of the Underground Railroad--to practice historical thinking skills and meet the criteria of the Common Core standards.
