Illinois Social Science Standards became effective in January 2016. Learning experiences in history, geography, and economics are provided to children in the District 2 social science program. Children study citizenship, community, cultures, freedom and justice, government, human rights, and natural and human resources. In addition, all schools shall hold an educational program on the United States Constitution on Constitution Day each September 17 to commemorate the September 17, 1787, signing of the Constitution. However, when September 17 falls on a Saturday, Sunday, or holiday, Constitution Day shall be held during the preceding or following week. The curriculum also includes a unit of instruction on the Holocaust and crimes of genocide, including Nazi atrocities of 1933-1945, Armenian genocide, the famine/genocide in Ukraine, and more recent atrocities in Cambodia, Bosnia, Rwanda, and Sudan. In all schools, the curriculum includes a unit of instruction on the history, struggles, and contributions of women, and a unit of instruction on Black History, including the history of the African slave trade, slavery in America, and the vestiges of slavery in this country, as well as the struggles and contributions of African-Americans.
