The Year We Had Two Thanksgivings tells the story of Thanksgiving 1939. In 1939 Thanksgiving was going to fall on the last day of November which caused merchants to be worried about a shortened shopping season. In response to this concern President Roosevelt proclaimed that Thanksgiving would be moved up one week. Some states chose to ignore this proclamation and celebrate Thanksgiving on the last day of the month anyway. The conflict was finally resolved in 1941 when Congress passed a law stating that Thanksgiving would always be celebrated on the fourth Thursday of the month. The Year We Had Two Thanksgivings is supported by ten primary source documents. Included in those documents are letters from merchants appealing to FDR to change the day of Thanksgiving and letters opposing the change.

Students can explore the facts and myths through the eyes of a Native American child or through the eyes of a female Pilgrim.

My favorite part of the investigation is "The Path to 1621" in which students hear the perspectives of Native Americans and Pligrims about events prior to 1621.
